Anyone had personal experience with the H2X Master Spas pool (Michael Phelps endorsed pool) vs. Endless Pools designs. Saw the H2X at a trade show, but did not swim in it. I was a little concerned by the turbulence, and the inability to change speeds quickly. On the other hand the finish and quality of the pool looks very nice. Endless pools have a very good history and I assume lots of folks will have a good opinion of them. Just curious if the H2X should be given consideration. Or others for that matter.
