We attempted to use Sani Sticks. However, we usually use cold water. When the Sani Sticks seemed to fail, we put in another...and another. Soon our drain was clogged up with Sani Sticks. Apparently, they may work as a prevention if you use boiling hot water...maybe.
The device I used pulled out several of the Sticks but the others are still clogging.
Bottom Line: No, I would not recommend this to a friend
