It shows a very sturdy heavy-duty construction, a button to keep it open without the need to constantly press it and tire yourself, and a release button once you finish so that the mechanism does not remain under constant pressure after you finish your work.

I would have liked it to have a call option or a second snake-type nozzle, which would have a call/angle function. Because it doesn't reach difficult narrow areas, such as the top part of the air conditioner where I want to clean the internal filters and from the top, which is very close to the ceiling and doesn't fit.

For €7, I definitely recommend it. It will also come in handy in the bathroom for salt and vinegar.

Update: September 18, 2022, it broke. It leaks the liquid through the nozzle, but it also leaks through the indentations on the handle, clearly indicating that there is a leakage in its seals.
