What can I say - I find it works better than gel cleaners.
I also like how it rattles and bubbles in the waste after use 😀

I've tried some gel drain cleaner before, but nothing much, so I wasn't expecting anything from this one either, but I was very pleasantly surprised. I poured hot water into the drain, then poured in the cleaner and miracles happened, it started to hiss, sputter and smell, so I preferred to leave it like that, after a few minutes I rinsed it again with boiling water and the drain drains almost like new! Great!

It kind of stinks, but what else would you expect?
