## Customer Reviews

### ⭐⭐⭐⭐⭐ Accurate
*by H***N on October 28, 2023*

Easy to use and read. Accurate results. Used to test free chlorine levels in a small community water system. Easier to use than a colorimeter.

### ⭐⭐⭐⭐⭐ Gives a consistent accurate measure of free chlorine in drinking water.
*by A***R on December 3, 2025*

I use these to test the free chlorine level in the water tank at our off grid cabin.

### ⭐⭐⭐⭐ Better than some of the other test strips. But.
*by S***S on April 6, 2022*

I have tested 3 different brands of test strips over a 7 day period and they did not correlate at all. 0.2 to 4.0 That is a huge difference when you are drinking the stuff. If you simply need to check if you have chlorine in your water these will work. If you need a definitive number go with a Taylor chlorine kit instead. For reference: I check my drinking water tanks for free chlorine every morning. When it gets below 0.2, I add 2.5 teaspoons of (drinking water approved) chlorine granules to a 2500 gallon tank. For our water usage, it will last a week before I need to chlorinate the tank again.
