7 in 1 Pool and Hot Tub Test Strips-125 Spa Test Strips for Hot Tub | Swimming Pool Test Kit for Bromine, Free Chlorine, pH, Total Alkalinity, Hardness, Cyanuric Acid and Total Chlorine

Accurate as near as I can tell. Easy to use. Would purchase again.

Accurate and inexpensive.

Good pool tester. Simple and easy use

This is a large pack of 125 pool/spa testing strips. They were a great value and cost less than major brands that only give 25-30 strips. I found them to be accurate and easy to use. Clear instructions and good color. I find them to be a quality product and I will buy them again. My only suggestion is to have an app that could take a picture of the strip and give reccomendations. That was the only thing I could see that it lacked.

Used it immediately. I used to have these, then stopped using for some reason. Used a strip immediately. Almost no chlorine, no wonder I have some algae. With temps increasing the pool eats it faster. Quick, easy, accurate, saves trip to the pool store.

Perfect pool strips, my husband doesn’t do well with high chlorine levels so I check it often to be sure Im not overdoing it

Dip the stick, read the color. Easy until many of the colors on the strip don't line-up with the guide. Won't buy again.

Love these
