We call them throw away tubs, same with all budget hot tub brands, i personally wouldn't trust such a huge purchase to a store who didn't have service people on staff, knowledgable staff (chemicals, troubleshooting, problems ect) you get what you pay for basically, not just including the product but the service (which imo is just as important)
edit: also you need to look at the other lines they carry, brands like aruba, you can't expect their other brands to be much better
