Overall not a good experience. Wouldn't recommend. The overall price is expensive, even after discount. As mentioned by previous reviewer, they will try to push you to sign the contract during the first appointment. Btw, they typically offer better discount in local magazine than here, say $700 vs $600. For the products, the water filtration should be able to filter chlorine and heavy metals. It's very matured technique used by all the water filter products on the market. They can't test whether heavy metal is removed, but they will do the simple tests to check if the water still has chlorine. But here is the argument, the chlorine is added in the water to kill bacteria, if the system removes the chlorine, then does the water filtered by the system still as healthy as they claim? Yes, the water right after the system is ok, but how about the water in the pipe? will the bacteria grow in the pipe? During the appointment, they claimed that their water system can generate water with well-balanced PH value, and they did the test for the water PH value, which is around 7.5. But actually later we figured out that the reason that PH value is good is simply because it is good even before the water system. We did the test, and the company staff came later and did the same test, we both found the PH value is about same before and after the water system. So basically the water system has nothing to do the PH value, you get what you originally get. For the hard water treatment, actually in the beginning, we didn't have plan to install hard water treatment, but during the appointment, they claim how bad the hard water is, and how good their product is, so eventually we also bought the hard water treatment device. Bad decision!! They said the water in San Diego is very hard, which can clog your water pipe, damage your skin. But in terms of clogging water pipe, later when I talked with my friends, some guys, who have been living in San Diego for more than 30, 40 years and live in 1950s houses, said they never found clogged pipe and they don't even have any kind water treatment system at home. One guy mentioned he even cut the water pipe before, and found it's very clean inside. Ok, at least, it can still damage the skin. Well, is it true? It actually all depends on how good the hard water treatment is. As they claimed, the device can make the hard water "softer". However, as they mentioned during the appointment, the device changes the format of the mineral, instead of removing it. Thus the mineral is clearly still in the water in whatever format, the amount of the mineral is same. So where does the "make hard water softer" come from??? The water is hard or soft is only checked by the mineral amount, not matter what kind of format. Actually if you google their patent, which is highlighted in their website, the patent US 8157971 B2, "Electronic pool water treatment system" background mainly talks about the "de-scaling". Therefore, the system has nothing to do with the "water softening". What they claimed was very misleading!!
