Sani Sticks break easily, and once broken, Sani Sticks wash right down the drain and do not remain within the drain trap. It’s like dumping money down the drain. Most packages that are on store shelves are broken in two or more pieces. Plus, after placing lemon scented sticks in the drain and leaving them overnight in a closed bathroom as a test to see if there would be a noticeable fresh scent in the morning, I found no scent. Also, we went away for three days and I expected to smell lemon scent throughout our home after we came back and there was absolutely no lemony scent. Do not buy.
Bottom Line: No, I would not recommend this to a friend
