This thing does NOT stay cool consistently.  Because I spent a lot of money on this thing, I after-marketed the crap out of this to get it to cool my beverages the way I like.  (Pictures to come)
I added two 240mm usb fans to the back to rest against the cooling plate and blow air forward towards the door.  I also added a 40mm fan to sit on the top shelf and blow air down to the lower level.  Then I added a suction cup soap dish to the glass of the door, off to the side to hold the USB Battery that powers the fans.  Under the soap dish hangs a digital thermometer to monitor temperature.
With all the after-market stuff added, I can get this thing, somewhat consistently, to around 35 degrees.  Unfortunately, the fans, battery, door shelf and thermometer take up space that would be slotted for beverages.
I will say this, the cooler itself is sturdy (heavy and solid), and is VERY well insulated.  The sides and the compressor in the back do get very hot, so it is best to keep it at least 5" away from walls and such.  This thing defrosts very quickly, so if you turn it off for longer than an hour or so, you will have to mop up inside and sop out the water in the back drip-tray.
I wish it cooled more by itself, but it is a cooler and not a fridge or a freezer.
