We've had it on the floor for about 5 months now. I really like the idea Hotspring was going for with the automated system, but it takes a few good reads to understand all the steps involved with setting it up. Once you get a hand on it, it is a breeze to keep chemistry properly balanced. Here in the DC metro area we do not have to do a lot with calcium and ph because most water supply is city water. So the only thing you have to do is test the water every 2 weeks and feed the results into controls, the only manual step. One thing that I have found is for a few days after chems have been added the water gives of a very gaseous fume. It can be a little choking at first, so I usually turn the jets on for a minute or so to let the gases release themselves. One other thing, being that it uses Baqua, you have to live with the hue of the water. Baqua water is very different than other methods of sanitization. Water has a slight clear tinted hue. When you turn jets on water really clouds up, which baqua always does and takes several mins. to clear back up when jets are turned off. All in all I like the concept, My feeling is, AutoFresh would be a great option for someone who has a Hotspring at a second or vacation home. Being that you can go two weeks without doing anything to water is a great relief for any homeowner. I feel most homeowners who have their spa at main residence really want to have the newest latest thing, kinda like the guy who purchased the first HDTV. Doesn't make since to me. Most homeowners will still use either the freshwater system or chlorine.
