Very reliable, easy to use and read the results. I find it very accurate on the chemicals needed.

Easy to read and fast acting test strips. Helped get my pool from cloudy to clear.

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

I find these to be as accurate as any other similar strips. The chlorine, the hardness, and the alkalinity are easy to read. the ph is marginal. The CYA is difficult to read. Overall, these are good but not as good as a liquid chemical test. I run a saltwater 25k gallon pool.

As a pool owner, maintaining the right chemical balance felt like a constant battle. The JNW 7-in-1 Pool Test Strips have quickly become an essential part of my pool maintenance routine, and I can confidently say they live up to their "quick and accurate" promise.What sets these strips apart is their ability to test for seven crucial parameters in one go: Free Chlorine (yes mine is low in the pic), Total Chlorine, Bromine, pH, Total Alkalinity, Cyanuric Acid (CYA), and Total Hardness. No more feeling like a backyard scientist trying to decipher confusing liquid reagents. With JNW, it's a simple dip, wait a few seconds, and compare to the color chart on the bottle. The colors are vibrant and distinct, making interpretation straightforward even for beginners.I've found the results to be consistently reliable, giving me the confidence to make the necessary adjustments to my pool chemistry.The bottle contains 100 test strips, which is a generous supply that lasts a long time, even with frequent testing. This makes them not only effective but also a cost-effective solution compared to some other testing methods on the market. The packaging is also well-designed, keeping the strips dry and protected from light, which helps maintain their integrity.For anyone who wants to simplify their pool maintenance and get reliable readings without the hassle, the JNW 7-in-1 Pool Test Strips are an excellent investment. They've saved me time, frustration, and ultimately, helped me keep my pool sparkling clean and safe for swimming. Highly recommended!

Work well. Developed color could be more vibrant though.

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 as expected - easy to read and use.
