Review summary

Created with AI, based on recent reviews

Looking at 21 reviews, most reviewers were unhappy with their experience overall. Many customers reported that the smart pool monitoring devices stopped working after a short time, suffering from severe battery failures, charging issues, and incorrect sensor readings. People felt that the steep price was definitely not justified given the poor quality, short lifespan of the equipment, and frustrating maintenance procedures. However, some reviewers were happy with the customer support teams when trying to resolve technical problems. Consumers mentioned that representatives were frequently attentive, helpful, and provided replacement parts quickly during initial troubleshooting phases, even though these efforts could not always prevent ultimate device failure.

Don't waste your money

Don't waste your money! I purchased directly from their website last December and by July (6 months) I started having battery issues. It would only last about a week and half before needing to be recharged. I contacted support and they said they would send me a replacement unit. Two months later and no replacement and it won't take a charge at all now.

E-waste

E-waste. Worked ok for a year, then many readings off, then just died. Not a long-lived product at all. Not worth the money

The ICO-V2 battery went dead less than…

The ICO-V2 battery went dead less than two weeks after purchase and use. They ask you to send a video, and then they don’t return your inquiry. It’s over $400 (US). This company needs to be reviewed by the BBB and sued for false advertising and deceptive practices. Good luck, US buyers.

too often battery failure

Bought an Ondilo ICO and had constant issues. Received a replacement and that worked fine for just over onr year, then the battery was no longer chargable and went down in one day. Of course that was outside the warranty so I was given a 10% discount if I buy a new one. We did last April and all worked just fine until the battery was down and needed recharging. We charged last week and now we are already down to 45% of battery.

If they run, they are perfect.
But the battery life is not what we expect from a device of that price. As it now is the third device with the same issue and always just after the end of the warranty, we are looking for an other product. Ondilo ICO is simply too expensive if you need to get a new one every 15-20 months 😢

Hello,

We are sorry to hear that the ICO has not been performing as expected since you purchased it in 2021.

However, we would like to point out that, under the manufacturer’s warranty, Ondilo has carried out three after-sales service interventions, acting in place of the retailer. We understand your disappointment regarding the battery life and would like to provide you with the following information.
The ICO analyser’s built-in battery is designed to last for several seasons. As with other electronic devices, battery life depends on numerous factors, including:
· Off-season storage conditions (temperature, humidity, battery charge level when stored),
• Intensity of use (seasonal or annual use, quality of the Bluetooth or Wi-Fi signal),
• Conditions of use

As the warranty period has now expired, we are unfortunately unable to replace the device or its components under warranty.

We would like to remind you that our products must be used in accordance with the instructions provided, as these are essential to ensure their proper functioning and longevity.

The company has no customer support

The company has no customer support. I did the 6 minth calibration as requirws, but it failed. No reason provided by the app. Best I could do was schedule a customer support call IN 10 DAYS. 10 DAYS. Are they kidding???? The worst customer service ever. DO MOT BUY!!!!

Hello,

We’re sorry to hear that you’ve encountered difficulties whilst calibrating your device.

We can see that a request was submitted via our contact form yesterday. Our team will look into it and get back to you as soon as possible. The usual processing time is 2 to 3 working days.

Regarding calls to customer service, these operate on an appointment basis to ensure personalised support for each user. All our agents are on hand. This year, we have also opened slots on Saturdays. However, due to high seasonal demand, slots may unfortunately be subject to longer waiting times at this time of year.

Kind regards,

Super support! Faith restored!

Well it all started well and the Smart pod worked super well with reasonable accurate readings relative to test strips and other meters. However, after a few months it went wrong and various emails the main unit was replaced. Hurrah!! It worked again but not so many months it started asking to be recalibrated and the comparative results on the strips started to separate significantly! However, after reconnecting with the company my faith has been restored. Their support is excellent and they diagnosed the issue and sent a replacement part. Their level of support is above and beyond. Thank you!

Hoping to get my warranty part! A super hope this product works and will continue to work…. It’s really amazing when it’s working, but Tech Support is frustrating due to them being located in France

Updated review…. I had a lot of problems contacting this company to get technical help. It is a bit frustrating because you have to set an appointment to talk to somebody in France in the middle of the night a week in advance. Not something we used to do here in America…. There is a third-party company that handles minor issues via chat, but they weren’t able to help w/ my problem. I think they’re just hired to help with basic setup questions. The gentleman from France was really awesome and helpful. They said they’re gonna send out the part I need because my product is still under warranty & is no longer working at six months. I hope they do! When a company offers a warranty, they really need to stand behind it . When this product is working, it is really amazing…. This is my third company I have used for a pool monitor and of all the monitors. This one I find to be the easiest and best. (when it’s working). If I get the part I promised, and this unit works as it designed to work for at least the year that was warranted. I will update my review to a five star. In response to the companies response….. there was obviously something wrong with your online contacting form. I requested contact via your form half a dozen times and all I got was an auto reply that you were “working on it.” no further contact was ever made and as many times as I replied to that email, I never received a response from the company or any help that way. It was very frustrating. I did explain that to the gentleman I spoke to in France and he said the system had been down…. I don’t know how long it was down for, but I tried a lot! So saying you replied to my request within 24 hours doesn’t really count when it’s an auto generated email that doesn’t do anything but acknowledge the fact that I sent a request. It would be awesome if you could fix that feature and we could email you guys and get Tech Support through your website….. even better if you listed your email on the website, we would be able to contact you that way! (in case you are having technical difficulties) :) Thanks!

I’ve had the ICO for 2–3 years

I’ve had the ICO for 2–3 years. It doesn’t work anymore. It has always been unreliable. I ended up spending extra money on a new sensor and a new calibration kit, only to find out that the module itself is broken. How do they even break just from being in water—that’s what they’re designed for, right? At that price, I would definitely choose something else next time.

We're sorry to hear about your experience. Reliability is our top priority, and feedback like yours helps us improve.  We understand the frustration of spending money on spare parts that were not in cause in the issue you were facing. That is why we offered you a discount on the replacement module to ease the cost — the offer still stands. Please contact our support team so we can assist you personally and hopefully restore your trust in ICO.

ABSOLUTELY USELESS

These people and the smart pod are absolutely useless, my pod has been sitting on test for more time than it has been in my hot tub in the last 18 months while they do absolutely nothing. Neither the product or the support (or lack of) work!

To resolve the issue with your SmartPod, we would ask you to return the device to our partner for analysis, testing and recalibration if necessary.
Our aim is to return it to you in perfect working order and to regain your trust. We remain fully committed to resolving the issue completely.

Overall, a Disapointing Experience - Ref ##81275# RDV Tel

I bought a Smart Pod last Summer. I have to say that the system itself (monitoring PH, sanitising, heat, etc) is/was fantastic. However, when it came time to recharge the battery and calibrate the pH and ORP sensors things went wrong. The battery would not charge above 28% - finally it bounced to 100% but it would not retain its charge and we now have to recharge is weekly (or most recently after a few days). When it came to recalibrating the sensors, one sensor would recalibrate whilst the other did not.

I reached out to the support team. They looked at my pod remotely and could see that there was a problem. Said that they would send parts and in advance of sending them that I needed to provide a receipt which I duly did by return e:mail. That was in very early February. I was told I would receive parts and the tool to change the battery, etc. However, in the middle of March nothing had been received. I chased and was told that the invoice had been raised (zero value) and that my parts were about to be sent. Today almost a month later still nothing received. I have sent a chase e:mail but haven't had a response yet.

This piece of kit is amazing when it works. The help from the Support Desk is excellent but they can only do so much - someone clearly has not followed-through with send out my parts. At this point, I feel that Ondillo should refund me or send a completely new pod.

Over all, very disappointed hence I can only award two stars.

Update:

The next day, following my review, Ondilo responded. As good as their word a replacement was sent immediately by courier and was received a few days later. Very quick response indeed. Hence I have updated my star review from a two to a four.

Hello Amanda,

We’re sorry to hear about the issues you’ve experienced with ICO and fully understand your frustration.
Your order has indeed been delayed due to an exceptional system glitch at our supplier’s end, which is a very rare occurrence. It will be dispatched today.
As a gesture of goodwill, we are including a calibration kit with your order.

We sincerely apologise for this inconvenience.

Useless devices.

What an unfit for purpose these devices have turned out to be, lve fought for two replacement ICO through Hydrolife so in reality that’s three devices lve had now, my son is on his second device, Ondillo responses in the past have useless and l will never buy another from this company, issues range from unable to connect to device, device showing sensors are not in contact with water, no Bluetooth connection amongst others. The issues will these devices has become so bad that Hydrolife are no longer stocking or selling them, that should be the Red Flag that tells everyone not waste your money on them.

We regret that your experience with the Hydrolife Smart Pod has not met your expectations since 2023. We have reviewed your correspondence history with our Support team. We were unable to find a ticket for your first device. We assume that you contacted Hydrolife directly, who proceeded with a replacement without requesting a diagnosis from Ondilo. For the second device, Hydrolife opened a ticket with our team in August 2025 and Hydrolife proceeded with a replacement. For the third device, which has been in service since September 2025, the latest measures were taken this morning. Our Support team remains at your disposal for any questions. Customer satisfaction has always been at the heart of Ondilo's concerns. From the outset, our customer service department has always dealt directly with all support requests for all users, whether they purchase an ICO product or a partner brand product, such as Hydrolife. This approach is in line with our spirit of service and transparency, with a view to simplifying procedures and providing a rapid solution.

Don't waste £400 on this, Unreliable!!!

Bought a Smartpod June 2023, had a few problems setting up which was rectified. Great bit of very expensive kit whilst working. July 2024 needed recharging, then totally died. After long painstaking communications with Jacuzzi uk who i bought off and Ondillio, i finally was sent a new pod V2, i thought great, no issues now, but earlier this year on calibrating a sensor had broken off, Ondillio said out of warranty and sort myself, no help. Jacuzzi sent me a replacement partially used sensor free of charge which was good customer service from Jacuzzi UK. Swoped this over and carried on using no issues. Came to recharge again and guess what, caputt battery, the pod only works now if plugged in as the battery won't hold the charge, so useless. Definitely won't buy one again, will use test strips again, and try to find another brand. The pod is a great idea when works, but is very unreliable, the parts inside and battery must be very cheaply made. Expensive waste of money, good luck to all that buy!! Communications are a challenge with Ondillio!

Hello Jeff, thank you for your loyalty since June 2023.
Customer satisfaction has always been at the heart of Ondilo's concerns. From the outset, our customer service department has always dealt directly with all support requests for all users, whether they purchase an ICO product or a distributor brand such as SmartPod, via our online store or from a reseller.

When you purchase an ICO device, as a consumer, you benefit from two distinct types of warranty:
• The legal warranty of conformity, applicable when you purchase your product from a professional seller.
• The Ondilo manufacturer's warranty, which covers your ICO according to the specific conditions defined by Ondilo.

Ondilo has always taken responsibility by sending replacement parts, often acting on behalf of the retailer and fulfilling their obligations.

We understand your disappointment regarding the battery life and would like to provide you with the following information.
The built-in battery of the ICO analyser is designed to last for several seasons. As with other electronic devices, battery life depends on many factors, including:
• Off-season storage conditions (temperature, humidity, battery charge when stored)
• Intensity of use (seasonal or annual use, Bluetooth or Wi-Fi signal quality)
• Conditions of use.
As each user has different conditions, battery life may vary.

The Ondilo team remains at your disposal for any further information.

Expensive and Poor Quality

Don't waste your money on one of these. I am on my third unit having had it replaced under warranty. It has failed again, got very hot whilst charging and now completely dead. I followed all instructions, removed Sensors and dried it out.

Purchases item and after nearly a year, the item just stopped working.

I had to request a call for someone to call me and go through the details. I found the call very efficient and I was promised replacement parts.

Now these parts never have been received, they have provided a tracking information but not to my address.

We are sorry to hear that you have encountered difficulties with ICO. Following the opening of your ticket in December, we did indeed send a Smart Core on 16 December. According to the carrier's tracking link, the package was delivered. Following your reminder on 31 December, informing us that you had not received the package, we filed a claim with the carrier in early January. Unfortunately, for international shipments, the carrier may take up to 30 days to respond. We apologise for this situation, which is beyond our control. Despite the lack of response from the carrier, we have just sent a second shipment.

ICO units are constantly faulty

Similar experience to other reviewers. Purchased an ICO unit 2 years ago and it’s great when it works but that isn’t for long. Had several replacement parts and probes sent out whilst under warranty but it keeps breaking. Now after the warranty has expired their suggestion is to buy another one. Going back to strips.

Nous regrettons que votre expérience avec votre Smart Pod n'ait pas été satisfaisante. Notre service client a toujours traité directement l’ensemble des demandes d’assistance, pour tous les utilisateurs, qu’ils achètent via notre boutique en ligne ou chez un revendeur, un produit ICO à notre marque Ondilo ou à la marque d'un distributeur comme Smart Pod - Hydrolife. Cette démarche s’inscrit dans un esprit de service et de transparence, afin de simplifier les démarches et d’apporter une solution rapide à tous les utilisateurs. Le revendeur demeure légalement responsable de la garantie légale de conformité. Néanmoins, dans le cadre de notre garantie fabricant, notre entreprise a procédé à l'envoi de plusieurs pièces détachées. Nous ne pouvons malheureusement plus prendre en charge l'envoi de nouvelles pièces. Bien entendu, nous restons à votre disposition pour vous accompagner dans tout diagnostic technique.

Have had one problem after another

Have had one problem after another. The company keeps replacing the ICO core every time there is an issue unfortunately the new one only lasts 6 or 7 months. The company then replaces the ICO core and probes but few months later it goes back on the blink. To be fair to Ondilo customer service they went out of their way to resolve the problems by replacing new ICO core. My personal experience has not been good. It works well for a few months when it’s new and then develops issues especially the PH probe seems to a major problem. I would not recommend buying this product. The next time mine develops a problem I will throw it in the bin and use the strips.

In response to your reply
I don’t understand the reason to return the Core. If the replacement was new which I have no doubt it was, then you should have confidence in your product’s performance. So the old Core and new one have the same issue of wrong PH data. Common sense would say perhaps the Core is not the problem but the PH probe is faulty. I have ordered a new PH probe so wait and see what the outcome is.
To correct your reply to my review. The reason for the first replacement was not because the probes broke but the issue was with PH incorrect readings. After the new ICO Core arrived there was a problem with the probes that broke while trying to remove the probes from old core to insert in the new one. I still don’t understand what exactly you think I did to those broken probes? I followed the instructions that was given to me and I have also offered to send you that core with the broken probes for you to investigate what might have happened.

Thank you for your feedback.
Following the difficulties you encountered, we have already carried out two replacements. The first case was when your probes broke: a completely abnormal situation that we had never seen before. The second case was in early September when your device was out of warranty. Our priority is to help you find a lasting solution to the problem and ensure that your ICO is working properly. That is why we recommend that you return the main unit to us so that our teams can examine it in the workshop and make an accurate diagnosis.
Thank you again for your trust.

I did have problems with the service was incredible

I have an Ondilo water meter in my Jacuzzi in my garden. Unfortunately, and I had some problems with the pH readings. When I originally reported them, I did get a call back but their solution did not work and I was forced to reach out again. I have to say, I am overwhelmed and amazed by the attention I have received. I was contacted by the principal of the company who personally helped me diagnose and find a solution. He followed it up on more than one occasion and I have to say the service was overwhelming. I am so impressed and grateful for this level of service. It’s actually quite refreshing in this day and age.
