SINCHER Pool and Spa Test Strips, 3-in-1 Swimming Pool Water Testing, Test PH, Chlorine, Bromine, Hardness and More, Water Chemistry Tester Kit, 50 Pcs

Does not work - just to be sure I tried the strips on pool water, tap water, distilled water, other liquids - it was the same colours all the time. - I tried them all.I also had two separate bottles of this product, tried all packets in all bottles. DOES NOT WORK.Garbage. It's an "Amazon's Choice" product as well....

The color is not correct from the first time I open the package (free chlorine is light gray) I tried it with several water sources, with other test methods the result is not accurate at all.

Very good

I think is not working always same resultDo not pay this!!!

False indicator
