Color blind?
I have a problem with the ph reading on the test strips. I have yet to see the strip turn a color that lines up anywhere with colors on the side of the bottle, making the strip useless. The color is not the same tint or hue so I am not even able to guess at whether the ph is too low, too high or right on. I have not had any problem with other strips.

Great, easiest to read...
I have used many different test strips for my spa, these are the best.
Clear high contrast indications, love them and will buy more.
