I purchased a kit to upgrade my Bitaxe. Everything was perfect except for the shipping, which took over a week to be processed.

NerdOCTaxe Pro is a scam
For second time you I trust on Bitronics and NerdOCTaxePro product doesn't work (PSU FAULT). I paid customs, duties/taxes here on my country for garbage. Also I sent an email to them and they don't response anymore. if you value your money and time, It's not worth buying here

I placed the order on 21 June 2026, but as of today I still haven’t received anything, nor have I received any information as to why there’s a delay. I don’t know who to contact because I was never given a contact email address.
I’m still waiting

A Very Good Home Miner—But There Is Room for Improvement
I find it a shame that on a miner—which typically runs 24/7—there aren't even fans for the voltage regulators on the back, or at least mounting brackets for users to install their own fans. There should be an option to configure better heatsinks and/or fans. I can certainly imagine that if you were to offer this—for instance, the option to configure two 120mm fans complete with mounting brackets—quite a few people would take you up on it! 😉

Thank you for your honest feedback. We’re glad you see it as a very good home miner. Your suggestion about better heatsinks, extra fans, and mounting brackets is very useful, especially for a device that runs 24/7. We’ll share it with our team for future improvements.
Great product just missed 5 stars…
Great product just missed 5 star due to customs fee. I know you mention it on the site but it could be obvious with a rough idea of what the fee will be. Mine was over £100

Thanks for your honest review. We’re glad you like the product. We understand your point about customs fees, and we’ll look at making this information clearer on our website. Unfortunately, the final amount depends on the destination country and local customs.

There was a problem with my new bought Octaxe (PSU). After several alalysis-tests product was replaced.

Thank you for your review. We’re sorry about the PSU issue, but we’re glad our team was able to identify the problem and replace the product. We hope your Octaxe is now working well.
Honest review
Honest review, this product is great. However, there should be an option to use higher powered fans. I have to keep my house at 70° F or it overheats. With summer upcoming it’s going to be difficult to do that. My other bitcoin miners run fine at 72° F room temp just fine.

Thank you for your honest review. We’re glad you like the product and appreciate your feedback about the fans. We understand your concern, especially with summer coming, and we’ll share your suggestion with our team.
