Bests & Worsts Reviews from Amazon

I got these to see if my kitchen sink was hooked up to soft water or hard water. With these strips I was very quickly able to figure out that the hot water from the sink was soft water, and the cold water was hard water. I was going to put off testing until a day when I was less tired, because I thought it would be complicated to figure out and to do correctly, but I decided to look at the instructions to see how difficult it would be. It turned out it was super easy. The colors made it easy to tell what the levels were for e such of the 16 tests. It also made it clear that our tap water is free from lead and other contaminants which was reassuring. I highly recommend these strips.
