This unit is about 9 years old and has been drained for the past year. Everything mechanical works fine, heater, filter pump, lights and ozone sanitizer. It could use a new cover but the original is functional. Some minor insulation missing, squirrel I think, but that could be replaced with a can of "Great Stuff". Perfect size for one to three people. http://www.hotspring.com/Spa_Showroo......
