If you're looking for an easy and reliable way to maintain your water quality, look no further than these fantastic test strips!

Easy and quick to get test results.

They work good and are pretty accurate for a while. I keep them inside and air conditioned but they seem to be a little inaccurate after being open a couple months. I check my pool twice a day and it still takes a while to use them all. They are accurate and I will continue to buy them, I just wish there was a better way to preserve them.

Super easy to use and results are easy to read with guide on the back of the bottle. I will buy again and highly recommend.

We maintain a semi-public pool and spa and are required to test and record both pool and spa water daily. We have used EASYTEST 7-Way Pool Test Strips for several years. We have compared their readings with other, supposedly more accurate, test methods and have discovered, time after time, that EASYTEST Strips show the same results. These EASYTEST Strips are accurate and very reasonably priced.

These were working good until I felt the strips were faulty the past months. I even tested against my house water, then purchased another brand with higher ratings. I know these strips need to stay in a cool dry place and they were kept in the storage steps container. They basically lasted a year. I now see the product does say use within 150 days after opening which makes this product a waste of strips, and the new brand I bought even worse now that I see it says use within 90 days. Probably best to keep the strips inside your home cabinetry and it is what it is with the shelf life.

Bought these strips to test my hot tub water. Quick and easy to use. Readings appear on strips within seconds. Good price for the amount of strips received.
