The bit that actually works
Look, I'll be straight with you. I had a bathroom sink that was draining like it was doing it reluctantly, taking its sweet time every single morning. Tried the usual boiling water trick. Tried a basic liquid unblocker. Then picked up a can of this mostly out of desperation.
The foam format is the thing here. You stick the nozzle into the drain, give it a few seconds of spray, and it expands into the pipe rather than just dribbling down the sides and doing nothing. Left it 30 minutes, flushed with hot water, and the drain was noticeably faster. Not perfect, but noticeably better.

Who this is actually for
This is for slow drains and mild gunk buildup, hair, soap scum, that sort of thing. It is not a miracle worker for a properly blocked sink. If water is just sitting there refusing to move at all, you need a plumber or a drain snake, not a foam spray.
Also worth noting: you need to actually leave it long enough. People who say it doesn't work have usually rinsed it after two minutes. Give it the full half hour.
For under two quid on S&S, it earns a spot under the sink. Especially if you've got a household where hair and soap are a regular drain nemesis.
