Wow! I was about to write a scathing review because I tried it on every body fluid for a week and the color of the strip didn't change. However, something stopped me and I read the seller's statement that the color does not change if the liquid being tested has a neutral pH. I decided to try other liquids that I know are acidic. The strips worked great! I'm excited! I love that they are made out of paper instead of plastic so they can be washed or thrown in the trash without adding any more toxins to our world. Color change at neutral pH. This saves consumer frustration and reduces negative ratings and reviews.
