Coolizi Reviews 

The product is complete rubbish. It has a weak fan that might cool a small toilet, certianly not a habitable room. I have requested a refund and am returnng the products. Wish me luck!
Questo prodotto è una vera schifezza. Ha una ventola poco potente che riuscirebbe a rinfrescare al massimo un piccolo gabinetto, ma di certo non una stanza in cui si possa vivere. Ho chiesto il rimborso e sto restituendo i prodotti. Auguratemi buona fortuna!

I will agree with all the other bad reviews- it does not work. BUT what is worse - the 30 day money back guarantee. It will cost you about the same price you paid for the unit to return it to China. Yes, you pay for the return. Now, will I see the $$?

This is NOT an air cooler, it is a fan SCAM, DONT MAKE MY MISTAKE, ITS A CON, guises under many different names like Solyball \Coolizi and many more, they all look the same, IT DOES NOT WORK AS A COOLER, nothing more than a cheap heater/fan, by Libizi, and dont try and return it, Please dont be led down the Garden Path, MSN Internet have been told, but if they pay they display. DONT DONT DONT.

After what felt like an archaeological dig waiting for it to arrive, my 92 yr old mother finally unboxed the miracle cooling machine she had been promised. Turns out it's just a fan with exceptional self-confidence.
The advertising paints a picture of icy rooms and blissful relief. The reality is a gentle puff of lukewarm air that couldn't cool a cup of tea, let alone an actual room. I've met people who can blow harder after climbing a flight of stairs.
It's the sort of product that relies on you lowering your expectations rather than lowering the temperature.
For the price, you could buy a proper fan from a reputable retailer, have enough money left for a takeaway, and still end up feeling less mugged.
Whoever decided to market this as an air conditioner deserves an Olympic gold medal for imagination. Calling it "cooling" is technically true in the same way standing in the shade is climate control.
An expensive fan in an air conditioner costume. That's all it is. Do not buy!!!!!

As an Engineer this unit appears to be just a fan!!
The heat in a room has to be dispelled usually to the outside. Heat will not just vanish. this unit defies the laws of physics. Do not be misled.

Scam,
As an engineer, I cannot find any meaningful explanation on how it works. They created fake review sites to mislead readers even more.
