Ive visited the ones in the Cleveland area. Its 3 guys out of a storage room in Willoughby, Ohio. 2 retired cops and a retired postal worker. They also sell furniture as well.
They bring the spas in from a no name manufacturer, cant offer any warranty or service. But, as I was told "Who cares about that, youre getting it so cheap you can afford to get it fixed and still be ahead of other well known models."
Ok bubba, if you say so .. LOL ..
