This is garbage, I have used pH strips in a laboratory environment and have never had a problem with them. But this one consistently gave me the wrong values especially at pH below 7. I confirmed this by comparing the results against pH drops and a meter. The meter and drops were concordant 6/6 times, while the strips where always giving values higher than the other two. Don't waste your money on these.
