From what is shown on their kickstart site they are simply a very small portable airconditioner powered by a battery. Lots of complaints on their site so caveat emptor.
Sorry I cannot help with actual reports.

Good Luck.

Unless it is a toilet you are proposing to cool, then forget about it. Even a toilet would need to be insulated.

Thanks folks we will forget it.

I think Zero breeze is innovative and has potential in certain cases. It's meant for small areas without power like a boat. 4.5 sq meters is advertised. The price and the rotary compressor is questionable as you can buy a portable aircon with go in it for half the price if you the power available. I will get one for my boat in March 2017 when they become available if I can find a supplies in Australia and will report back. So far it seems American based.
