These were SO easy to use. I was able to instantly tell if there was too much peroxide in my pool. I am new to this and so many other ones needed certain other things for testing. But these strips you just put in the water and it instantly (well, a few seconds later) shows you the color. It was very easy to read, no mistaking the colors. I will buy again.

The colors between levels are different enough to be useable. Note this is a wide range of peroxide levels, often more than typical spa usages, but if you need to pinpoint higher levels, this gets the job done! It would have been nice to have more in between levels specified by a color on the bottle, but it is useable nonetheless.

The test strips have 1 job to do. I believe they useful but I would not expect them to be entirely accurate .They give you a color range to compare the test strip to. Standard stuff. Somewhere in a range of color and you get the ppm.But sometimes I get colors that are not on the chart. Don’t know what to do with that. Sorry but the product needs improvement in order to get five stars.
