Excelente servicio

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.

Great Price! And great to support the Driver Community!

Ordered a boat seat cooler. The picture in the description appeared larger than the actual size. I could tell as soon as I received it that it wasn't going to be the size I needed. I contacted them to ask if I could return it and they responded quickly with approval for a return even though I noticed on my receipt that it wasn't an item that you could return. Overjoyed they worked with me on this!
