Hey,
We bought a Prodigy a few months ago mainly for therapy. My wife has degenerative disc disease, and I have arthritis and type 2 diabetes. We looked for a tub that was good quality, not too big, and didn't have overly powerful jet pressure, as my wife's condition is quite sensitive to pressure on her back. The diverters let us each tailor the therapy nicely. The Prodigy fits the bill quite nicely for us, but if you want a tub that is very powerful, then you could be disappointed in your choice.
