This wine cooler is just as advertised.   After delivery, allowed to stand overnight before plugging in.  Unit quickly reached the default temp of 54 degrees F.  Moved about 100 bottles of wine from a malfunctioning old unit, over 3 or 4 days.  Each time temperature fluctuated a small amount, but quickly stabilized.  
Unit is best for regular Bordeaux type bottles, but can accommodate several Burgundy types also.   Some of the larger champagne and Burgundy type bottles will not fit into a closed shelf.
I organized my collection by shelf and bottle number.   In order to identify the shelf numbers, I printed the word processed encircled numbers onto clear mailing labels and attached these labels to the corresponding shelf fronts. 
Very quiet operating unit, has a little hum during part of the cooling cycle, but much quieter than my older WineMate cooler.
