Water Hardness Test Kit-150 Strips Water Quality Testing for Drinking/Well Water, Softener,Hard, Dishwasher,Pool,Spa, 0-425 ppm

good

These test drips are excellent! There are many of them in the container and they read the water quality very accurately. Very affordable. And it gives me great peace of mind to know that my water is good quality. Highly recommend.

Very handy for RV when traveling, lots of different tests on one tab. It will also test the wholding tanks. Easy to read.

Worked as it should.

Perhaps I have a faulty batch, but these are impossible to read. I kept thinking my water softener was not working and got these to see if it was kicking on the recycle like it should. I've done 3 tests and not one come close to matching a color on the legend. I have no clue how you are supposed to actually tell from this what the hardness is.I reached out to a neighbor who had a different kind of kit where you put little scoops of a solution into a test tube and it is super accurate and easy to determine what your water hardness is.This is inexpensive, but far as I can tell it doesn't actually work.

Great

The instructions should be updated that the strips need to be read at exactly 30 seconds. If you wait even 1-2 minutes, most of the color changes back to green and the edges become even more orange (see test strip on the left in the picture). So you need to set your timer and take a picture at exactly 30 seconds.

I got these, so I could make sure my water softener was working. I liked how quickly I got the results and it just took one strip. I am sure there are other uses for these, because there are 149 more test strips in the container.
