Anybody have one? They claim to stay with 2 degrees of fill temp for 30 minutes due to the insulation and warm air induction. If you have one, is this true? Putting a new one in for a bathroom remodel, and the sales lady swore their showroom model could be filled at 9 am and would still be warm (not hot) at 5 pm.

Well, reporting from the history of jetted tubs,
the ideal experience always came from Jacuzzi jets and only Jacuzzi tubs had them and no jet parts were sold to competitors, ergo a corner on this market.

Further, Jacuzzi did for awhile take on partners when seeking an ideal tub material, which was discovered to be Acrylic; thereafter, parners were dismissed and could only become copy cats w/o the real deal jets.

So others may be able to advise on temperature controls, other bells,whistles, et al. but my next tub demo/remodel will be Jacuzzi and perhaps not the big box store Spartan models.

I can assure you, this is not a big box store brand or model.

I got that, ref was all about Jacuzzi and which I would select
