Drinking Water Test Strips 9 in 1 by MHT - Drinking Water, Ponds, Aquariums, Test in Seconds for Total Chlorine, Alkalinity & pH, Metals

Product seems to work fine but could never find what correct levels should be. Product does not give you any scales or reference to where you can find scales (that I could find). You get many test levels but unless youŕe a chemist you have no idea if theyŕe good or bad. Found many many websites and never could get a straight answer on what is high, normal, low...

The bottle came with two sealed bag of stripes, it have good accuracy reading at the first two days, after a week, the rest of the stripes at the opened bag is bad, don't have accuracy reading at all, for the full price getting around 5-6 good testing result.

Bought these to test my water, and the effectiveness of my water filter setup. They seem to work, but some of the readings are hard to read. Depending on lighting conditions it could be one value, or the other. I suppose that is true of any types of these test strips.

Not a meaningful test for lead. Thought the product description mentions the EPA's poor regulation of water quality, this strip cannot tell you if you are below the EPA's action limit. I'll be purchasing something else for that. Too bad.

This kit doesnt include any information about what safe levels are of each thing it is testing. Now I can tell you what my the levels are, but are they safe levels? No idea.

So I'm a bit skeptic when it comes to new things-like a dipstick test that indicates lead levels. I gave these a shot when I ordered them from Amazon, and tested my Classroom water at school. Good, no lead indicated. But the I immediately asked myself if there WAS lead, would it show up? Lead nitrate solution used, and it did show a variety of levels depending on how much I put in the water. So, yeah, they worked and I figured I'd write a review in case anyone is interested in testing their water and wanted immediate results. It is a test strip, so you can only get an estimated value or range, but it is much easier than sending a water sample out every time (and less expensive for less than $20 for 50 strips).My only recommendation would be that they create and include a laminated card that has the test values on it. With 9 tests on a curved bottle it's sometimes difficult to make sure the strip is easily compared. It's fine as is for the occasional test, but we'll be using these for some high school level labs and will be doing quite a few.

They don't work. I followed the directions very carefully, and all of the test strips came out nearly the same color they were to begin with (with the exception of alkalinity appearing different on one of the three strips from the same glass of water? Not sure how.) The three test strips I have pictured on the left are all from the same glass of tap water. The one test strip on the right is from my Berkey filtered water. I know these strips are not accurate. I can smell the chlorine in the glass of tap water, and the glass of filtered water has no smell. Yet, all the strips say no chlorine in the tap water, which I know is chlorinated. The other photo I have posted is a plug from my filtration system, which separates the tanks between the tap water and the filtered water. You can clearly see the discoloration caused by the tap water on the plug, where the other half is not discolored by the filtered water. Clearly, there are some differences between this filtered water and tap water. Well, not according to these worthless test strips. I am so upset that I wasted my money on these. I feel robbed.

It tests multiple things in the water which is nice but the water hardness is very hard to read. Use something else if you want to test your water hardness levels.
