## Customer Reviews

### ⭐⭐⭐⭐⭐ Very accurate for me
*by  on Reviewed in the United States May 25, 2026*

I have always had good luck with the accuracy of Taylor test kits. Every now and then I double check with local pool shop.

### ⭐⭐⭐⭐⭐ If you need it you need it
*by  on Reviewed in the United States December 11, 2023*

If you run a hot tub, you need to be aware of your water's pH. Test strips are too inconsistent and difficult to read. The Taylor reagents work with the Taylor comparator and provide a reliable, consistent, repeatable test. I only maintain my personal hot tub so the 0.75oz 'A' size is perfect for me. These should be thrown out a year after they are opened, even if the expiration date has not passed, according to the manufacturer.

### ⭐⭐⭐⭐⭐ Worked
*by  on Reviewed in the United States January 15, 2025*

Works like it should, not much else to say about it.
