I am dealer, and I sell the Limelight tubs. I have one running on my showroom floor, My wife and I have wet tested all three models over the past year or so. We like them - when I sell my 25 year old classic out of my backyard we are strongly leaning toward replacing it with a Limelight.
I have sold a bunch of them since they were introduced, and I have spoken with other HS dealers who have told me that Limelight was selling real well in their stores. I think we have a winner here. They seem to have a good combination: the Watkins name behind them, lots of flash and sizzle, good power with lots of jets, steel frame, and yet they are usually priced just a bit lower than HotSpring tubs. That can vary by market, of course.
Works for me.
I have had tons of trouble with the lighting system in the tubs we sent out the very first year. The repair was easy - plug in a new control box under warranty. Takes less than two minutes. When bad, it shut down the whole spa, but once you unplug the light control the spa comes right back, and I finally figured out that this was going to repeat and I began to stock the little control box. Easy fix - but they upgraded the control system which took care of that problem nicely: you won't have a problem with it now. Then the lights themselves had problems, but Watkins either redesigned or changed vendors, either way it seems to have corrected THAT problem. The rest of the tub was made up of components from the regular HotSpring line, (all well-proven stuff) so I have had no other problems with the tubs. Our owners all report being very pleased with their tubs.
