So after a couple of days of ownership I'm really impressed.
We've seen it cool down to -2 so far.
We've got it in to a routine whereby its on during the day and off at night, as we don't really need it on during the night. It would still be quiet enough to have on overnight I think if it wasn't too close to you.
It cooled my Cider cans down nicely which I'm pleased about and I'm not sure why I'm surprised but it just works! I think I expected it to be a bit duff, but as I say it cools really well.
