It seems to be of very good quality for a decent price. I put 4 - 3' tabs in to start and it did a pretty decent job. They don't last forever, far longer than any other one that I've had before though.

Excellent product, easy to use and the 10ft pool we have now smells like a clear running water river. Highly recommend!!!!

This little guy is great! I use it for my inflatable 10x6 pool. I wonder if this would be sufficient when I get a hot tub one day...
