So far so good nice cool, heavy duty.

Never came with a battery, the wrong wall plug and does not sit level. It does seem to cool, but briefly used it once.

I bought it to go camping, it fits more than a 40qt and cools very well. The only bad thing is that the battery lasts less than 24 hours at the recommended temperature.

Great cooler, well built and not cheap construction. I got the first one and all was well till I updated the firmware then things changed. I had a brick. F1 error and I was stuck. Anker sent out another one when I sent it back and thus far things are golden. I will NOT be updating the firmware until I know that it will not brick the cooler.

After a month, we can truly say that we have put this cooler through a very thorough testing and are delighted.
