2020 Hot Spring Saltwater Highlife Envoy Hot Tub, uses salt cartridge, includes built-in blue-tooth speakers, RGB Led lights and has 3 different zones. Fits 5-6 people comfortably and has a lounger and a captain's chair. I have two filter sets so that one set can be cleaned so the hot tub can continue to be used while the other set is being cleaned. Comes with a hot tub vacuum. I bought it in June 2023 for $22k from HotSpring Spas -- I love it and works well; I haven't had any issues. I'm moving and unfortunately, I can't take it with me at this time.
