Product review (3 stars): Works reasonably well
This is my first wine cooler so I have no basis for comparison. If you buy this unit, ignore the temperature settings and buy a good digital thermometer. I had to set my cooler at 45 degrees to achieve a temperature range in the low to mid 50's. There is a difference in temperature of about 4 degrees between the top shelf and the lower shelf. As Fall approaches and the ambient temperature is cooling, the readings are getting lower. This morning my lower shelf read 49 degrees.  My house only got down to about 64 degrees last night. Be sure you are placing the cooler somewhere with lots of ventilation. At first I placed it in a large walk in closet allowing plenty of space around it on all sides. The unit ran constantly, heated the closet, and never achieved a temp below the high 50s. Moving it into my office solved that problem but that was a disappointment because I wanted my wine out of sight. I have some nice Syrah that I wanted to keep cool. Those bottles would not fit on the regular shelves. By removing the bottom rack I was able to shove in 3 bottles. I could also get those bottles into the two outside spaces on the top shelf. I have had to work with it and make adjustments but it seems to be functioning reasonably well now. I may be unrealistic but for $300. I had hoped for better than reasonably well. I have had the unit for one month so I can't comment on how it will do over the long run.
