it is a nice tub, Part of the Hot Springs line of tubs under the umbrella of Watkins, Also have Caldera, LImelight, Hot SPot., It is right up there as a top tier spa line with , D1, Jacuzzi, Sundance, to name a few.. as myself not a fan of the salt systems. On the Ace it is still fairly new to the market i believe roughly a year or two, give it a little more time and see how it fairs. I know the Hot Springs guys like it. I thought i liked the salt systems until my customers starting haveing too many issues... I know they have been pretty good, but i do not think they have been out long enough to be proven... there were a few posts on this forum and the other if i recall that there were a few issues with the sytem, But again is a very good brand. But personally on my own spa have ozone, Vision cartridge and chlorine, 5 minutes a week of maintenance...
