16 in 1 Drinking Water Test Kit Strips, 100 cnt. Home Water Quality Test for Tap Water, Pool, Spa. Strips for Water Hardness, Total Chlorine, Mercury, Lead, Aluminum, Fluoride, Iron, pH and More

The test strip instructions and match comparison to the test result chart were easy to understand and use. Rather then relying simply on the taste of the drinking water after Reverse Osmosis treatment, wanted to actually know what we were drinking and received an easy to read composition of elements and their strength. We got a clear reading and were happy to learn there were no harmful elements in our drinking water. Next, we will be testing our regular house water for softness/hardness. We are confident this test will be equally simple to perform. We are happy with our choice.

The customer service is great. As it is a container of two 100 count packs I wish the shelf life was a bit longer after a pack is opened. Just 90 days. The strips mostly read as they should although I did have a couple of inconsistencies from one strip to the next. I was able to contact customer service through e-mail and their Youtube channel for guidance.

This water test kit came as advertised -- perfectly sealed bottle under the lid, and with two sealed packets inside dividing the test strips in half. Easy to use -- my only issue was after testing, where excess water on the strip could cause color runoff from one test pad to another (which may affect accuracy due to color mixing). The instructions do say to "carefully shake off any excess fluid" but maybe I just need more practice? For this same reason, it would have been nice if the color guide were laminated (in case water were to fall on it).

I got the same results, testing tap, filtered and bottled water. I live in the mountains with quality well water, its just hard water, but it shows high concentrations of fluoride. A lab test showed no fluoride. How can I have fluoride in my well water? Also, the stripes are hard to read, because the chart they provide is not the same scale size, so it is very hard to compare because they don't line up side by side. Think I wasted $20, only because I cannot trust results.

These test strips are easy to use and there are a lot of them in the box (allowing for lots of testing at a decent price), which is why I chose them over similar products. I followed their directions exactly and tested them on 6 different sources of water (shower filter, fridge filter, 2 different under-sink filters, as well as 2 unfiltered sources) at multiple locations. I didn't experience any running colors like some other reviewers mentioned. I know my filters are working to some degree because they make the water smell cleaner and taste cleaner vs getting unfiltered water from the tap. Regardless, these strips gave me the exact same color results for all 6 sources of water, filtered and unfiltered. Apparently all 6 sources are super clean and free of chlorine, fluoride, etc. That, or these strips simply change color based on whether they're dry or wet. Maybe I got an old box and these don't work anymore? Whatever the case, I can't recommend these.

They were very easy to use and get results. It was also a great value.

Love that these strips are able to let us know all of the different things that might be in our water, as well as the alkalinity levels!! Now I know that not only does our well water taste delicious, it is totally safe, with no chemicals and also is alkaline and not acidic!! Such a nice thing to know!!

I think this set of filter paper strips does what it's supposed to do! You can't compare it in terms of accuracy to lab tests. If you're looking for that kind of accuracy, you should just send your sample to a lab. What this strip does is that it can give you a ballpark indication of what's in your water. Or at the very least, a positive / negative indication of presence / absence of a compound. It did take a couple of tries to come up with a technique. Other reviewers have mentioned that the colors tend to run, and that does happen. But I'm pretty sure the same will happen with other brands of strips with multiple tests on it, and there's more than enough strips to experiment with. I found that if I used a fork to put a small drop of water onto each square while the strip is laying flat on a paper towel, I can get by without having the colors run into one another. Of course you should rinse the fork with the water you're sampling thoroughly before using it, and change forks for different water samples etc. For the waters I tested, the strip showed that the tap, boiled tap, bathroom tap waters all have higher pH, alkalinity and hardness when compared to my filtered water, which makes sense to me. I was actually looking out for lead, but I guess there's no lead present in the waters I tested.
