Seems to work well. I checked the kitchen faucet for 147 then I checked my reverse osmosis system and it read 82 which sounded too high. Tested distilled water showed ZERO. I called the reverse osmosis manufacturer who made me replace 2 of the 5 filters and now I was looking for 8-14 where it should be. The device seems to be working fine. Satisfied.
