I thought Sani Sticks would be the greatest thing invented. I realized, however, that they are actually stopping my drain up because all they do is collapse and curl up like a little snake and stay in the bottom of my drain. I've been putting one down for about six months, and well, today, when I took my piping apart, there's six sticks still intact and caught in my drain. Besides that, all they did was make my drain almost completely charcoal black.
Bottom Line: No, I would not recommend this to a friend
