We have nothing to hide. We will tell you the pros and cons, and show you the differences in spas -- shell materials, insulation, siding materials, plumbing, equipment, operation cost, installation, repairs, etc. We explain why someone would throw away a spa and buy a new one. We are not afraid to talk about the problems. Most manufacturers use inexpensive materials and manufacturing methods to make their spas as cheap and fast as they can (for bottom line profits$$$). You only learn how great they are about trivial things, not the meat and potatoes.
