Product review (2 stars): Actual Temp Is Much Warmer Than The Set Temp
I  had the temp set at the lowest setting of 38 degrees.  Beverage was cold but thought it should be colder for 38 degrees.  So, I decided to put temp probes to see how it compared to the setting.  My hunch was correct.  The temp probe was app. 5-7 degrees warmer than the set temp.  No matter what I did, it was significantly warmer: turned it off overnight, tried different temp probes, check both ends of the temp setting range, probed all levels, etc.

Everything else about it so far is very nice.  I just can't get over the temp discrepancy.  I'll probably return it since I bought it to have very cold beverages.
