Ordered wrong part...customer service was fast on first order but a little slow on the second. Returns were hassle free so far

Great price for assembly + tank.

Easy website to use, easy checkout with multiple payment options.

Fast shipping great customer service

Boatplicity was good, FedEx was not. The refrigerator arrived on its side. It was not secured in the truck. It fell over a pallet and it dented the side of the refrigerator. Fortunately it did not effect the functioning and is not visible once installed.

Been looking for these

great A++++++++++++
