These test strips are easy to use and they work well. We just got a pool and these have been helpful to check chemicals and determine if what adjustments we do are working!They’re super easy to use and read. The color accuracy is great.

These pool test strips make daily water testing easy. Just dip in the deep end away from the wall and you have your reading in seconds.I find them to be mostly accurate and the value propostion is good.I buy them all the time.

Simple and accurate. All you need to keep your pool sparkling and clean (except a vacuum)

This a great, but sometimes the chlorine/bromine tab will be completely white but when testing with my drop test it tells me there is sanitizer in the water. Sometimes it hard to read the pH, but it's not too bad.

Prefer these over the 5 or 7 way test strips. These strips test for the 3 important components that I look for, and readings are very accurate.

These strips are the best I’ve used, out of four different brands. These are the most accurate, and the immediate results are clear and easy to read. So glad I finally found a keeper!

I have been buying these test strips for years. They tell me everything I need to know, without being overly complicated. Store them dry and they keep working well for more than a year.

I use this product to test the water in my hot tub. I find this product easier to use than other products I have tried. This is the first time I ordered it on line and It came very quickly and is exactly as was described in the ad.

Les mesures des bandelettes s'avèrent exactes, je les ai croisées avec des mesures fournies par des professionnels pour l'eau de ma piscine. Ça correspond exactement. Personnellement je recommande ce produit.

Funcionan al instante y la composición del agua se comprueba muy fácil gracias a las instituciones que vienen en el exterior del bote.

Fantastic value with 50 test strips included. It can be tricky to match the colours up though and I have to take a best guess, even under day light. I don't know how accurate it is, but when comparing a range of different water samples it becomes easier to see which sample is better or worse than the others. I'm using it to test different sources of drinking water and under different conditions.
