It is incredibly easy to fill with air; with 15 pumps that have no resistance at all, it reaches 4 bar, meaning in about 20-30 seconds it is ready to use.

I tried it on a clogged bathtub, the first time I didn't hold it well, I did a second pump that fit well, and a third just to be sure.

In about 3 minutes I had used it 3 times and the bathtub was unclogged. Very useful tool for every home.

I used it to unclog a sink where a plastic cap had fallen inside. With the pump it has, I put in 4 bar of air and that was it. Any other classic method I tried did not solve the problem. Of course, in sinks with an overflow hole, you need to close the hole. I used a cork.

It's a waste of time. I tried it in sinks and the bathroom, and within a few days, they got clogged again. I didn't see any difference at all. Additionally, when you try to fill it with air using the pump, it becomes a hassle

I used it in a toilet that was clogged, and after 4-5 uses, it was completely unclogged. I had used various chemicals but with no result. Now, for the sink, I haven't needed it yet, so I can't give an opinion.

Excellent. With one use, it unclogs EVERYTHING and at the same time, I save money and effort from having to constantly buy disposable solutions.
