Product review (3 stars): Amazon was quick to provide me with another unit as I was not satisfied with this difference
The internal temperature does not match what the unit displays.  My first unit showed the temperature as 55 degrees.  I tested the inside temperature with two different thermometers and confirmed the temperature to be 65 degrees, 10 degrees from what the unit displayed!!  Amazon was quick to provide me with another unit as I was not satisfied with this difference, however, the new unit still shows a difference of 5 degrees.  The internal temperature stayed consistent, but for those who don't confirm the actual temperature can be storing their wine at a total different temperature than desired.
