### ⭐⭐⭐⭐⭐ Great price, Great product
*by S***H on February 3, 2026*

Was surprised to see Amazon had the cheapest price on these. They keep the water clean and dissolve at a good rate. They work great! Pair with Clorox pool tester steps to stay on top of chemical levels! There were a few chipped/broken tabs in the box, but nothing too bad.
