We have and we say. It is 2 dimensions, 10 and 12 centimeters. Its own tube is 10 and has a ring if you want to attach it to 12 centimeters. Unfortunately, it does not attach because the ring is 13 centimeters and it was forced to fit. For this reason alone, 2 stars. Furthermore, the noise is a little more than one from Leroy Merlin that I had bought a while ago for 10 euros. So, the conclusions are up to you.
