I needed a spa for my chronic pain, back injury, fibromyalgia. Didn't ever think I'd have these sorts of problems and it took me a while to clue in on hydrotherapy as a means to relieve my pain. It works wonders.
bought the Artesian Piper Glen after researching and wet testing many spas including Jacuzzi, Sundance and Catalina. If you're about to buy a spa without a wet test, think again. I completely changed my mind after testing the different brands. Perhaps the most significant difference with the Piper Glen was the force, placement and variability of the jets. I felt that the Artesian was hitting my trouble-spots in a manner that was improving the pain. It seemed like a "real" therapy spa, whereas the others were "nice," but not quite as "serious."
The other thing I liked about the Piper Glen is that it's simply beautiful to look at. The lights around the foot jets are spectacular at night.
There's nothing that I'm sorry I left out. I love having "chairs" rather than a "lounge," as I found that I float out of the lounge chairs. I got the "sand" finish, which i LOVE because it always looks clean, even if it could use a little rub-down. :)
There IS a common problem with the touch-pad on the Artesian Piper Glen -- at least the model-year I bought mine -- BUT it was fixed pronto and hasn't messed up again.
One thing I recommend is to add a little shelter over your spa -- either an umbrella or an overhang, as soaking in the rain is very nice for achey joints!
