These worked as intended and I was happy with the ease of use and value. Results were easy to read and use.

Strips do do not accurately read levels. By the time I realized this, return window closed.

Overall, the Water Hardness Test Kit - Quick and Relatively Accurate is an good choice for anyone wanting to easily and quickly assess the hardness of their water. It is simple, affordable, and effective for everyday use, and it offers a great value for those looking to ensure the quality of their household water. Whether you’re dealing with the effects of hard water or just want to stay informed, this kit delivers precise readings in an accessible and easy-to-understand format

Great product. Very quick and easy to use. Very simple to understand readings. Makes it much easier to maintain my pool. My wife will do the test and send me a picture and I can tell her what to add to the pool while I’m stuck at work! Will repeat buy!

These are pretty good. Cheap brands tend to show levels are higher than they are, not showing the mid range of color. More expensive brands tend to have less tests per strip so you need to buy more types of tests. This ones quick and easy showing both total chlorine and available chlorine, bromine, alkalinity, ph, and hardness

These strips are very easy to use and the results are easy, straightforward to read. You do have to work very quickly for accurate results but after using them a few times you’ll get a routine down and have no issues. They offer a free ebook/manual that provides very detailed instructions as well as descriptions of each chemical, the dangers of having too little/too much of it in your pool/spa and how to correct & maintain proper levels. You’re able to print this ebook right from their website as a PDF.Ordered these strips after clearing up algae that left us with insane cloudiness afterwards that we couldn’t clear no matter what we tried. Spent a few hundred dollars at our local pool store on all their recommended chemicals that didn’t work. Took in multiple water samples for them to tell us everything was perfectly within normal range but “here use this, it’ll clear ya right up”. These strips immediately showed us our chlorine & bromine levels were off the charts too high, alkalinity way too low. Once correcting those levels we’re slowly getting back to crystal clear water. I highly recommend these strips, we’ve added these as a product to purchase yearly for our very short Northeast Ohio pool seasons.

It is inexpensive, fast, and easy. Accuracy is questionable though, and that is problematic for me. I think I have gotten mostly accurate readings over the last several uses, but I did not double check all the measurements to test if what I think is correct or not.I cannot rely on these tests strips for an accurate reading of free chlorine today. In the first picture, the color range result for the free chlorine test strip looks like 0-.5ppm. It is the third row (the text strip is longer than the bottle). If I solely relied on this reading, I would have added chlorine to increase the chlorine level.That would have been a mistake. Yesterday, the free chlorine reading in my pool was 3.44ppm, which is a little high. I live in South Florida, and it rained yesterday and overnight, so I expected a small drop in free chlorine, but not this. I tested the water, immediately after this test strip reading, with a digital meter, and the free chlorine reading is actually 2.51ppm.I bought this product hoping to lower the amount of times I use more expensive test strips for my digital meter. Unfortunately, that expectation was too high. I would only use this product in between tried and true testing for a red flag.

Works well compared side-by-side with others I've trusted over the years.Good value too.
