These are excellent test strips.
Calico✓ Verified Purchase•August 5, 2023
These test strips work very well. I tested them side-by-side with the water hardness test kit that my water softener salesman used and the results were right on the money in every case. I use these periodically to insure that my expensive water softener is working properly. The results are immediately observable making them quick and easy to use. Update after first purchase, I have purchased additional test strips, they continue to work well.
Did what they were supposed to do

I bought these strips to test whether my new water softener was working or not. The strips were easy to use, and the colors were easy to tell apart.
Easy and Accurate

Very impressed with how easy and accurate these are. I wanted to make sure our softener was working and these helped prove that it was. The left strip is from the outside hose spigot that is not softened and the other 2 are indoor faucets. It may not be good to pin point exact hardness, but you definitely tell if your water is hard or soft.
These work perfectly for homeowner use

Accurate and distinguishable color gradient graph with instant results. Beware of other manufacturers that have rather indistinguishable color gradients
I already knew my utility water system entering the house was 17grains/213ppm of hardness through my local municipal utilities web site. These strips nailed the color accurately. After the water softener it's close to zero grains of hardness.
Allowed me to verify that all my water outlets were properly plumbed. The ONLY outlets in my home that produce hard water are the cold side of the kitchen sink, the cold side of the bar sink, the cold water feed to the refrigerator water dispenser and ice maker, the lawn sprinkler system and the two outdoor faucets. ALL other outlets (and mean all) are soft, yes, including the toilets. Don't let anyone tell you that just the hot water outlets need be softened - absolutely incorrect.

They are what they are.

If you need these for your pool, hydro systems, or just be sciency, they work. Wish the colors were a little more color blind friendly.
