Product review (4 stars): Very good wine cooler!
I received the cooler in perfect condition and have been using it for a week. It is freestanding in a room that is typically 73-77 degrees. There is 6 inches or more of space behind and on both sides of the unit.

I keep one side at 55 degrees and the other at 60 degrees. Since it is thermoelectric, the cooler will not go more than 25 degrees below ambient, and I have observed that it will only go down to 53 degrees. The top of each side stays about 5-7 degrees warmer than the bottom.

When first turned on, the fans will spin faster until the set temperature is reached. The fans will be exhausting maximum heat while it cools down, so leaving extra space around the unit helps it cool faster. After that, the fans slow down and the unit becomes very quiet. If the door is opened for more than a few seconds, the fans will speed up again for a little while until it cools off. If you put in many bottles at room temperature, it can take a few hours or more to reach the set temperature and the quiet fan speed. Also note that if you set the temperature lower than the unit can achieve, the fans will continuously run at high speed.

I find it useful to put thermometers in the bottom half of each side. If you find that it can't maintain at least 20 degrees below ambient, there may not be enough space around the unit. If it is cooling properly, but the fans are still running fast, try raising the temperature one degree at a time until they slow down.

I gave it four stars because it could be a little better at keeping the temperature uniform from top to bottom and it could benefit from another few degrees of cooling.

All in all, I am very happy with the wine cooler. I can keep both sides close to 55 degrees for storage or raise one to 60-65 degrees for red wine serving temperatures when desired.
