All-New 20 in 1 Drinking Water Testing Kit 120 Strips, Home Tap and Well Water Test Kit for Hardness, Lead, Iron, Copper, Chlorine, Fluoride

I use the test strips for my portable filter water pitcher to let me know is the water is balance. Than I test my facet water too.It allow me to hold back the filter in the pitcher a little longer than usual time . Try it !!

Easy convenient and shameful how bad water is!! Scary. But the strips are great!

haven't used as yet but good very professional

Bought these recently post the LAfires' incidents since we recieved a "no drink" notice from the municipal water department & since i did infact notice a change in color from out of our bathtub spout.[it was dark/ashy lookin' pressumably from experiencing low pressure as per the notice,so it was alarming to say the least] They are certainly made ready to preform their purposes but I would appreciate it if the sellers of these products were more,idk how to say this--perhaps "sensible" is the word: about the performance aspect of the product they provide & its "how to" work them. For ex; instructions state to submerg but not shake off the leftover/rendering water(presumably to not cross contaminate ea. Square test) but if you dont shake it off <properly>, the excess water bleeds over onto each anyway, leaving space for inaccuracies do to the testing properties of ea square.I did the slightly more timely/tedious process of "dripping" droplet/s carefully onto each Square so as to heighten those accuracy probabilities & it seemed to work in a more reassuring manner as it was noticeable that they wouldn't be bleeding onto eachother.I did water from a spring water bottle, my tap water & water filtered through a reverse osmosis system. Reverse osmosis was the most relatively clean/safe from my findings & im happy to be able to see a comparable difference between it & what is unfortunately still not the greatest quality running through my apartments pipes. [That is, what it is:*shrug*]..the bacterial tests were a cool "add on" <since they only provide what looks like 2 on the box>, but there's essentially 2 in ea bag[4 sheets total] of the exact same testing type of material (this blue paper) & again, instructions suggest that you simply pour water to what seems like less than a cm degree into the packaging bag it comes inside off & pretty much use up the whole 2 sheets, when you can surely break the sheets down into straps, submerge those really well in your own <clean/sterilized baggie> & recieve the same kind of "bacteria" results through this test type. I will double back in 48hrs w/ comments on the efficiency of my results. Pretty good/effective kit, overall though I'd say.

Great tester for the price

Did everything it claimed

As advertised, arrived fast

This was a good kit for the money, but I will say that I did not understand how the chart on the container was supposed to match the test strips. So I had to guess because they did not line up. However, all tests showed that we have a middle level of water, not soft but not hard either. There was kits for 3 different types of tests. Worth the money.
