Welcome to our forum.
I'm not buying a Jacuzzi, however...FWIW, I'm the type of person that even with an established company, I try to avoid the first year run of products....my son begged for the Xbox360, and I told him forget it for about a year, then we'll discuss...by then the "bugs" should be worked out. I'm the same way with cars....tubs may or may not be changed enough to worry over a new model (Jacuzzi's been around for a long time), but I think personally I'd be more comfortable with the more "tried and true" models.....This is my opinion, and it's subject to change at any time...
I'm surprised snowbird, that you think they filled up the 1st one and when it didn't leak and swirled water they pronounced it ready.
