Is that the thing I've seen on the commercial where it's a hot tub and has a current at one end so it is multi-functional. If so, those commercials are ridiculous ending with the overhead view of the guy getting a swim workout while 2 other people chat it up in the spa behind him. Bringing me to 2 important questions:

1) Who in their right mind would sit behind someone swimming that close?...the splashing would be ridiculous
2) How could they regulate the water temp in this contraption so that it's comfortable for a workout on 1 end and yet a hot tub at the other...if you're trying to tell me this guys going for a workout in 100 degree + water, then I'm saying you're crazy

If this is not the product you are talking about, sorry for the long rant. I always end up laughing at the end of the commercial
