Product review (3 stars): Ok but NOT ultra low temp.
Sturdy and well built.  Very quiet.  But I bought it because it was advertised as ultra low temp and I can't get it below 38 degrees F.  Turned it all the way up and that's as low as it goes.  I wish there was a way to adjust the thermostat which is the issue.  it is well insulated and doesn't run continuously.  If there was I might give this 5 stars.
