I tried a few thinking it looked like a good idea. Really just Green Gobbler BIO-FLOW but I've seen ads for others like Sani-Sticks. I like the concept that they just go in the drain and are supposed to stay in the trap while they slowly dissolve - up to 30 days - rather than an instant hit of bacteria/enzymes where the drain has to be kept unused for some time to allow them to work. However, I'm not sure how effective they are at staying in the trap. I tried putting one in a cup with water, and within a few hours it had started getting soft and curled into a circle. The photos they show are of them as straight sticks that seemingly stay because of the curve of the trap.
I have a kitchen drain that's completely white plastic pipes and I can shine a light and see what's at the bottom of the trap. I found that it started softening up where it was lying against the curve. I was using the sink, and I checked again after a few hours and the thing was gone. It just seems to me that they eventually flush out the drain like anything else that goes in the sink.
