I'm really happy with this! It tests the water immediately and has a great, easy to read display. It's nice knowing that my water is very clean. I bought this to take on my next cruise to test the water for salt. Can't wait to try it on the ship!

Good hardness meter

Can not tell how accurate is it but I don’t really care if it’s slightly off. Easy to use, instant result.
