I tried the Sani Sticks per the commercial review. It has cost me $550 to fix my plumbing because the sticks are a no-do. They do not help unclog your sink; they clog them. Per my plumber, the worst idea yet. I WANT MY MONEY BACK. For $9.99 per pack, rip off big time.
Bottom Line: No, I would not recommend this to a friend
