Roommate bought these unknowing to me and put them down my bathroom and kitchen sinks. I've noticed the kitchen sink slowly backing up and the bathroom is completely blocked. Thought they were doing a good thing to keep smelling it. But I use eight bleach and Pine-Sole cleaning the house, it wasn't needed. Now I have to hire a plumber to come to clean them out. Liquid fire and plunger not working.
Bottom Line: No, I would not recommend this to a friend
