The test strips are brightly colored with good color separation between results so they’re easy to read even in less than ideal lighting.

The colors on the strip during the test are impossible to distinguish.

They are easy to read (so long as you don’t have problems seeing colors, as some folks do).These test strips are a good quick-check for your water supply, and can help you determine whether further laboratory testing is necessary.
