Initially set upper temp to 45 degrees and lower to 60.  Temps were consistently displayed at 47 and 62...not a big deal.  But, after 4 days, the display on the upper zone changed to 93-99 degrees.
Wayfair customer support was awesome though and is sending me a replacement.

Pros: looks good.  size is right for our needs.  Wayfair customer support.
Cons: display malfunctioned after 4 days
