Enzymedica PH Test Strips -- 1 Kit
I would not buy these again and am sorry that I did. Compared to other pH strips...they are difficult to read. (The box says "easy to read") The color differences on the chart are so similar for 6.5, 7.0, and 7.5. And the color chart on the box it comes in is different from the color chart on the dispenser.

This product turns various shades of dark blue after using and I have found it extremely difficult to distinguish between the 7.0pH and the 7.5pH color because they are so similar. Plus the pH range only goes up to 7.5- I prefer a higher range.
