Product review (2 stars): Ordered 2, both failed and were returned
Both came well packed. Plugged both in and one failed to recognize power after 20 minutes. Tried multiple power sources and it never again recognized power.  After several days the other loaded cooler reached 51 degrees when 55 was the set point and nothing would make the temperature raise.

Supplier sent shipping labels for both and both departed. (I was glad I saved the packaging.) If I don't get a refund, I'll revisit this and change the rating to 1.
