These pH test strips are really easy to use. I like the two colors on the strip for a more accurate reading....most pH test strips have only a single color. These strips are sensitive and accurate . Really great! Highly recommend.
Certainly, these pH strips do the job of estimating the pH of urine or saliva. I will not purchase them again but will go back to the paper roll. These are little plastic strips. I'm deleting plastic use as much as possible. Also, a big to-do about a pH system is made on the outer label but no further information is to be found inside. I felt it was marketing and nothing more.
