Review: Simple - reliable - accurate pool test strips - These test strips seem to work much better and are far more accurate than other desertcart ones. The cheap bulk 6, 7 or more in one tests always seem to be all over the place and don't align with my pool company testing. These are a bit more expensive but a 50 pack will last thru the full season - vs throwing away half after 90 days with the larger packs. They are easy to read, the colors stand out and they are consistently accurate for my pool. Highly recommend!
