Does anyone have experience with the different brands of swim spas? I see many postings referring to Endless Pools (which offer a variety of different units), but I can't find any postings about Michael Phelps swim spas and their less expensive airless jetted siblings, the H2X Challenger series.
Acknowledging that these units are quite expensive, does anyone have experience with the H2X models? Would you recommend them? I am considering those because they are a bit less expensive and seem more full-featured.
