Customer Review

Reviewed in the United States on October 9, 2016
The rocks initially produced no results. But then I placed them into a 3 gallon ceramic water dispenser. The results were remarkable, I guess the difference is that all water dishes need to be rinsed out and cleaned and the chemical produced by the rocks rinsed away. With them always soaking in the water dispenser they work like magic. My newly sprouted grass seedlings are not even harmed. I also break the rocks into smaller pieces at the end of the month with a hammer in an old towel and get a second month out of them. I don't have to worry about the dogs choking on smaller rocks as the water dispenser will not let them pass through.
