Waste of money - Not what I wanted or needed

This product was a real waste of money. It says it is for pools as well as drinking water. Well, I didn't find it useful at all. It definitely does not work for testing pool water because it doesn't tell you the percent or rate of a chemical which is essential to know how much of a chemical to add to get your pool water corrected. It only shows colors if it is OK or not. That means nothing. If PH is like 7.2 it may be OK but it is too low for swimming pools. The same with all of the other chemical readings. I did exactly what the instructions showed but even so the chemicals are so close together that they bleed over onto other measures so you can't even tell if it is okay or not. And when I tested my tap water, it gave readings that are impossible and appear completely unsafe. But it is city water and tested regularly.
