My bathroom drain was seriously clogged, used a grabber to get a huge clog out, but the rest must have broken off in the bend. The "snake" in this was virtually useless, it did literally nothing to help break up the clog, and I'm not entirely sure it even got close to it. It was already bent from being wrapped around the bottle in the box, which you'd think would be helpful, but it wasn't. The gel is going down the drain super slow, and takes a half hour to work, so I guess I'll see how that goes and update my review.
Update: now that it's had time to work, it was completely useless. Didn't do a thing. $10 wasted. You know what DID work? A plunger.
