Works the same as similar ones and cost less.

honestly, i havent used them yet since my pool is bring built. looks great product as it is sealed good when i receive it. i will update the post once i use and check the accuracy. but so far it is value for the buck.

Works as instructed.

These strips are really easy to use and they’re pretty quick. They seem to work pretty good for the most part, but seem to have some slightly different test results when compared to some other brands, which makes me question the quality of these a little bit. I think they are pretty good, but maybe not quite as accurate as the more prominent and well known brands.

We have a hot tub, and for whatever reason maintenance products became a little harder to find last year, including but not limited to the chemicals and testing strips. We had officially run out, then found these. They work excellent, are a great value, and I believe their accuracy may actually be even better than some of the alternatives based on how the hot tub looks and feels after treating it according to the readings of these strips. The treatment can be tedious but keeping an eye on it is vital, and these strips make it easy to do so. Works great for all home spas.

These test strips are thicker than another brand I was using. It's a lot easier to read when the colored patches are bigger. They work.

This is an awesome set of test strips that cover a wide range of water testing parameters. I used this one bottle to replace two separate bottles of strips I had and this covers the same range of tests. They are very easy to use and did a good job of diagnosing water quality and imbalances.****As a product tester for Amazon, I take pride in offering honest and dependable reviews of products so that anyone thinking about purchasing this product gets a fair assessment of functionality and quality. If I find that the performance or quality of a product is reduced after I've made my initial review, I will update to reflect these changes.

Very good quality test strips. I find that using the liquid drops is a little easier to read but these are a good alternative and much faster. Just dip for 2 seconds and you have all the readings. I also don't have liquid drop tests for the conditioner it was nice to test that without having to take a sample to the pool store. Would buy again.
