Sturdy construction, it meets my requirements exceptionally well (cleaning of machinery, car, and difficult areas of the house after work)

I got it for testing. In theory, it was supposed to work well... in practice, it worked even better. Very good product. It greatly increases the amount of air

Very good and with the spare parts it gives you, it's like having 3 guns. The Venturi is perfect although it makes a little more noise. It sends the air with a slightly higher speed but over a much larger surface. The pressure regulator takes a little getting used to. It doesn't have fully open or fully closed, it turns wildly. Just every half turn you make goes from maximum air speed to minimum air speed and back again. You understand it better with the sound that changes depending on the speed. I've had it for about a month and I highly recommend it. Now if at some point it fails me, I will come back here to note it.
