Works great!

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!

Size is great

Easy to use got for a backup extra to have on hand if everyday tester breaks. Live it!

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.
