JNW 7-in-1 Pool Test Strips, 100 Quick & Accurate Test Strips for Pool Water, Spa Test Strips for Hot Tub, Chlorine Test Strips, Bromine, pH, Alkalinity, Hardness & More - Swimming Pool Test Kit

Bought to test HOA pool......Provided more information that I knew I needed. Easy to administer and read against the provided chart. Results were dead on.

Works great! Dip in water, add items for colors that dont match those in boxes. Turns jets on and wait 10-15 seconds to re-test. Colors for those items you added are now in the boxes! Easy peasy!

Not really sure how accurate test strips are. I get the same reading from tap as well as osmosis. Yet osmosis system is 400 ppm less.

Great product, I order it often.

These work pretty well. The coloring can vary a bit from order to order but overall works well enough. I believe some of these are just difficult to measure this way so not really their fault, but still usable. I very rarely need to pull out the pro kit.

Easy to use and quick to read. These help me keep up with my pool levels without guessing.

I don't have a pool, BUT my Urologist wanted me to use these to test my urine at home! I did what the doctor told me and am able to see what foods/beverages cause a spike in my uric acid! Dr. was right these are a lot cheaper than the ones sold for the same purpose in the drug store! LOL

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.

These are the best test strips I have used over the six years I have had a pool. As well as testing my water, I have tested the strips by adding measured amounts of chemicals into the pool water and checking the change in results. These strips are very accurate within the parameters stated. Very useful to have the CNA measurement which many strips ignore. The colour differentials are good and the strips are very easy to use. Buy these..!!!!!!!!

Worked well, just what I needed to test the effectiveness of my water softener.

Mucho ma fácil de comprobar Muy contento con el producto

Very good product, simple to use and good value.
