The product came with in the time allowed. It really didn't do what I needed it to. I am not happy with it. Nothing against who I bought it from.
Customer Review: Useless Summary: 1 Stars
This water "tester" cannot distinguish what's in the water. It will barely give you a reading. If one is using distilled water --which is the water I drink and use for cooking-- this tester will give a reading of ZERO particles. Aside of distilled water, everything else will get a reading of 120 or more. There are much better products out there that will give precise information not only concerning percentages but also giving on the contents in our water.
I tested distilled water, filtered water and tap water. According to this "tester" the filtered water in our shower got the same reading as the water coming from the tap. I do not need this tester to tell me distilled water is 100% pure because I know that already.
