The company had been easy to work with, though it’s unfortunate that now they have to have a homeowner at the house to do their tests even if the unit is accessible from the front lawn. The sales associate also didn’t mention anything about a maintenance program either which would have been good information to have prior to the purchase. Even with those points, I’m very happy with the unit. My water tastes very nice, and I can even tell when it’s time to put more salt into the system based off of how nice the quality of the shower water is, so it must be doing something. I got the cheapest unit but it feels worth the value.
