Finally I got one that worked, it took 3 tries but now I have a fully working unit. The first one, the top section did not work. WayFair sent a replacement ASAP and I appreciated that. The second one, well lets say maybe it was Fedex fault, but the box it came in and the unit were destroyed. it looked like Fedex employees tried to staple the box together. I took pictures of the box and unit and sent them to Wayfair. I received the Third unit and its been working like a charm for 3 weeks now, fingers crossed. It does have two refrigerator units in it and can be loud when there is no other noise in the house.
