I received a Cover Caddy from UPS Friday. I purchased at CostCo for $149.99 shipped. It was at my door in 4 days. I do like the return policy CostCo offers which I have used in the past on other items.
The Cover Caddy arrives partially assembled. The directions are poor but assembly is easily figured out. I did use the picture on the front of the box as a reference once or twice. The build and materials seem to be of good quality. The base plate is heavy gauge steel. I think it is just less than 1/8 steel. The powder coating on all parts is nice. The tool included is cheeeeezy. Use your own.
I will be using the bottom mount method. ( That doesnt sound right)
I dont want to be drilling into the side of the spa.
I will update once installed and throughout its lifetime.
