Pretty good products. I have the Refiner and a Reverse Osmosis System. So far, both have been good. As expected, the filters need to be replaced on a yearly basis for the RO system. I think the pricing is a tad high though. The installation for both was a little less than desirable. Recently had a water heater repair and the guy commented on the Refiner installation and how the connections seemed stressed out, noting how a few more angle adapters could make it better and safer from water leaking. Not too enthused to hear this but it is what it is. It's been a few years since install so I don't want to bother with it now.
