Pool strips work easily and effortless. Worth the money. Would buy again.

    • quick, easy to use, better color/contrast than many others
Style: 7 in 1 pool Size: 150 strips
I have some color blindness and cannot read some other brands of strips at all, and I would have to use "drops" based testing all the time. I still use the higher precision tests, just not every time...they are now just to confirm my readings, or for setup after drain/refill of my hot tub. I use these with a bromine setup and find it reliable and quick, and the precision is close enough that I have a chart of how much chemical to add to move up/down the scale of the test strip one increment making it "stupid simple". ... show more

    • Not so good -
Style: 7 in 1 pool Size: 100 strips
One of the main issues I encountered is that the results obtained from the test strips do not match the liquid test. The accuracy of the readings is questionable, leading to uncertainty about the actual levels of hardness, chlorine, bromine, free chlorine, pH, cyanuric acid, and alkalinity in the water. This inconsistency makes it difficult to effectively maintain and balance the pool or spa water. Furthermore, the quality of the test strips is subpar, as they are falling apart easily. The strips are fragile and tend to break or tear when dipped into the water or handled. This not only affects the accuracy of the results but also adds inconvenience and frustration during the testing process. Considering the price of the product, it is simply not worth the investment. The affordability of having 100 test strips initially seems appealing, but when the accuracy and durability are compromised, it diminishes the overall value. I would have expected a higher level of quality and performance given the price point. While the instructions suggest that the testing process is quick and easy, my experience has been quite the opposite. The color chart provided on the bottle is not always clear and can be difficult to interpret accurately. It takes longer than expected to obtain reliable results, which defeats the purpose of having a convenient testing solution. The inclusion of a free e-book is a nice gesture; however, it does not compensate for the shortcomings of the test strips themselves. The additional information provided in the e-book does little to improve the overall experience or address the issues with accuracy and durability. In terms of usage tips, the instructions recommend keeping the strips away from moisture and closing the cap tightly between uses. Despite following these instructions diligently, the strips still deteriorated quickly, further highlighting the lack of quality and longevity. Overall, I cannot recommend the Pool and Spa Test Strips. The inconsistent results, poor durability, and overall lack of value make this product a disappointment. I would advise seeking alternative testing options that offer more accurate and reliable results, even if it means investing in a slightly higher-priced option. ... show more

    • Quick and easy to use, but check within 30 seconds!
Style: Water Hardness Size: 150 strips
Review Image by Bernsie82 Bernsie82
I had a whole-home HALO5 filtration system installed recently and felt like our water was much harder than when we only had a water softener. Bought a box of these to check for hardness. Easy to use and the hardness registers almost immediately. IF YOU HAVE HARD WATER, you need to check them within 30 seconds or so, otherwise the color of the test changes (see picture). When the filtration guy came out to check the HALO5 system, he read the strip immediately, and after a few minutes and said it wasn't that hard. I asked him to use another strip and that they were supposed to be read within 30 seconds. Within just a few minutes, it starts showing the original color of the test strip (which is green for soft). You can still see some of the rust color, but the green definitely shows through. I tried this with distilled (soft) water and the test color showed very soft. After an hour it was the same color just a bit lighter. BE SURE TO READ THE STRIP WITHIN 30 SECONDS FOR ACCURACY! ... show more
