Bests & Worsts Reviews from Amazon

Save your $$$.. other products out there better. First of all, the hardness test is flat out wrong. Using a accurate dedicated hardness test of my water, it gives a reading of 50, which is low. However this test, says it is 250, which is good. A huge difference between 50 and 250. if I go by the wrong 250 reading, I'm in for some trouble. Next problem is the total chlorine test. it has a scale of 0 to 1,000. WTF. Who is going to have a lever higher than 3 to 5? Maybe if you are shocking it, it can go up to 20 or 30... but 1000? really. You can't even get a reading under 50. That's pointless. PH and Alkalinity test accurate, but the color is hard to determine. Summary, I'm, going to stay with my "Aquacheck" test strips. More accurate, and color is easier to read.
