I bought these strips to test some alkaline water and they came back negative (acid). I went to the company I bought the water from and told them they were fake. I asked the lab results to show the pH of the water and also tested the water with other strips and a digital tester. the lab showed results of 9 and other testers were between 8 and 10. I also tested other types of water with Alkazone "Accurate" Check Ph Test Strips only to find that ALL had the same reading! I want my money back!
