Cannon, with two blasts it unclogged the sink and I was saved from the plunger that did nothing, the plumber, and my wife's nagging..!!

Very good. With three attempts it unclogged the toilet, and if I had done it correctly it might have unclogged it on the first try.

The siphon was clogged with hair, I had tried everything and it wouldn't unclog, with this on the third press it cleared.

It does its job perfectly, it has been used 5 times for the sink, even if it saves you a plumber visit just once, it has paid for itself

I tried classic plungers, wires, pressure washers, nothing worked—after a few days or weeks (in the case of the pressure washer) the sink would clog again because there are bends in the pipes that run under the floor. With the gun, I managed to unclog it and months have passed without the problem reappearing. It is very powerful so you need to be careful not to cause damage. I used it directly at the mouth of the drain pipe so as not to cause more damage to the sink. Full pressure was not needed, I preferred to do it 4-5 times with reduced pressure.

Remember to lay plastic (bags) underneath and have old rags handy for the dirty water that will come back.

It did a very good job on the sink siphon where it was used. Many extra accessories for adapting it everywhere

The small safety often pops out, so I have to hold it. It helps with the initial unclogging only to necessarily add tuboflo

Excellent for household use, I relied on the comments. It immediately unclogged the sink drain, be careful with the instructions, there should be enough water to exceed the rubber part and also make sure to close the other "holes" that water can pass through, for example, in a double sink the second hole or in a basin the small overflow hole

The two exhaust/pressure relief valves open by themselves when you try to pump air into the device (if you don't put your finger to create resistance, pressure cannot be generated). I believe this is due to poor construction quality.

I had tried various things to unclog the drain on the balcony. There was sand and small gravel. 3-4 times with the plunger and the job was done!!! Five stars from me

The toilet unclogged with the first attempt. I had tried before with 100 methods and chemicals without success.

In tests conducted on unblocked pipes, it appeared that it does the job nonetheless and the flow was better.

Device made of cheap plastic that smelled like oil when I received it and took days to get rid of the smell. The usage is not that simple, it requires basic knowledge of plumbing and is not suitable for the average user. The drain pipe must be filled with water (thus blocked), the trap must be stable (not a plastic spiral), and the overflow of the sink/bathtub must be sealed in some way.

I bought it for 13€ and it does its job, but be careful because if you don't seal at least one of the other outlets of your sink or washbasin with a membrane, all the dirt will splash on you, that's why a bag for the toilet bowl is provided in the package. Of course, if possible, don't use the same tool from the toilet bowl in the sink where you wash your dishes. Personally, I wouldn't do it.

Where it fits well, it unclogs very well, as long as there is a little water in the pipes. Where it doesn't fit well, many times it still doesn't unclog perfectly. For its price, it is a good purchase.

The only reason I bought it is because of the positive reviews. I tried it in the bathtub and it had absolutely no effect.

I had a problem with the toilet and I had tried everything, from doctor's remedies with baking soda-vinegar, plungers, etc. With this, I solved the problem. Of course, it took me 5-6 shots but in the end, all is well. Very easy to use and effective.

Unbelievable. I didn't expect it to work, but in the end, it's super!! No more chemicals!!! I highly recommend it.

It is amazing and very useful against clogged drains from hair, hair conditioner. It works by applying pressure to a bottle that has a trigger and releases it. Perfect for narrow pipes that get clogged easily.

Very good tool and useful, it helped me a lot with the sink in my bathroom, but I won't say much, I have made a detailed video for you to see if it does the job or not. https://www.youtube.com/watch?v=C2EdMXnMHM0

It does exactly what it promises.

For better and more immediate results, make sure to close the overflow (bathtub and sinks)
and the floor drain.

Highly recommended!

If someone wants pipe unclogging (because the contractor did a "good" construction and installed a narrow pipe that constantly gets clogged), this is the ideal product. It leaves nothing behind, neither grease, nor hair, nor debris, nor residue, nothing. Very easy to use. The only requirement is to have stable pipes that need to be emptied, because when the trigger is pressed, the pressure applied is high...

Perhaps the most useful device in my apartment. Whenever there is a clog in the toilet or sink, the gun unclogs it in seconds. It also functions as a manual plunger if the compressed air is not sufficient.
