Had to send back the first unit as it would not hold temperature.  I found on the second unit that you have to set the temperature a bit lower than you actually want it.  I ordered some temperature strips to place on my wine bottles to confirm the actual temperature.  Had to set the unit at 55 to maintain a 61-62 temperature on the bottles of wine.  Other than that, I really like the unit.

I will also say that Wayfair's handling of the return of the first unit was OUTSTANDING.  The responded quickly, kept me informed of the progress, delivered the replace unit and took away the old unit - just as planned.  In a world where good customer service is starting to be hard to come by, I just want to say how well Wayfair did in providing great customer service!
