Here is my take on a Clear water Spa.
You can pretty up a turd with colored lights and shiny jets but it is still turd. You can spray a turd with enough perfume that it might smell good for a while but the stink will soon comeback.
Clear Water makes a pretty spa but they use low quality parts, poor workmanship, inferior shell reinforcement.
Ask them if they use Viton on the seal, geloy in jets, Incoloy 825 heaters, fiberglass backed shells, 316 grade stainless steel on the jet escutheons... Well if you ask they may say sure we do, so make them prove it.
I doubt most of them will even know what some of those things are.
They the things we cannot see but we appreciate them down to road in added longevity to the parts in the spa, which equates to you spending less money on repair cost or at least putting it off a few more years.
