I like that these come in a bottle instead of a booklet, as they are at a reduced risk of accidentally getting wet. They worked as advertised and store well.

The color guide is in shades of blue. Test strips return results in shades of aqua and teal. How are you supposed to match shades of different colors? Either fix the color chart or the strips to use the same color.

They seem to work but are VERY hard to read between adjacent values. I can use them to get a ballpark reading but wish the dye was easier to distinguish between different levels.

I use these for our daycare and while the strips are fine, the packaging and color match strip don't match up as clearly as other products we used. When we could be in violation for over or under ppm, the risk is significant.

Test strips worked very well for our use! Not as cost effective as test tape but still works well in a pinch.

Purchased for a super chlorination event where our standard test equipment will do up to 50 ppm. We were looking for 500 ppm so it was perfect. Some men have an issue distinguishing the color, however it is very easy to tell what the chlorine level is in graduations of 50 ppm. Measures free chlorine.
