Will not disappoint!

This a great product and I do recommend it. The container itself has many great features. First, the container is fantastic. It's a tub with an open/close lid that protects the product and seals in the chemical smells of chlorine. We've been using this product for six months without any issues. It dissolves properly in the chlorine dispenser and doesn't produce algae.

Ten tabs per container

There are TEN (10) 3 inch tablets in container I received. Nobody thought that was Important to put on the Made in China label. These work with the Large model pool floating dispensers. No issue with product. They are NOT individually Wrapped items so expect some breakage during shipping. You can compare prices against the HTH 2 pk, not sure what those cost. They usually last a week. Good to Go so far
