Product review (4 stars): 3 Years and still doing well
I have this installed under a counter and made sure I had air space on each side and about 1/2 inch above it. The unit has been working very well, it keeps both sides at the temperatures I set without issue. Even through power outages the insulation has held the temps well within tolerances (1.5 hours is the longest outage I've had). As a note, it is installed beside a dishwasher (4 inches of space between them) so the opportunity for outside heat influence to change the temperature is possible, but it still holds temp.

I do ding it for the noise of the fans. They are louder than other fan sounds from a U-Line fridge/freezer and are probably amplified by the under counter install as it creates a bit of an echo chamber.

I didn't realize it when I bought it, but a feature that I now consider essential for this style unit (in a bar, under the counter) is the tilted racks at the bottom of each space. We don't always finish all bottles in a sitting so having the ability to cork it and place the bottle back into a properly conditioned tilted rack is great! Nice for that special bottle of Port too. If you are considering or searching for an under counter unit for a bar as a staging area versus your wine cellar, or if you only need to keep 20-30 bottles of wine, feel comfortable this will work very well.
