very brittle, each is broke in several pieces
The price was good,  about 1/2 of the sticks were broke into several pieces,  the length makes them work, small pieces wash through the p-trap and are gone.  The sticks are too brittle.  I went back to Bio-Flow- Green Gobbler. I ordered several of the Lynwell sticks, I think I can save 1/3rd to 1/2 of them (there goes the good price).
