Excellent for its price. I use it on the veranda (pergola) with a patented removable drawer (hanging from the pergola). My projector (EPSON) has only three screws, one of which is for adjusting the arm's distance, so there's a patent there too, with the reuse of parts. It's not the base's fault, it's my requirements. Despite all the tricks, it moves very little with the wind.

It is quite good, it does its job well, rotates around the 3 axes, but it is a bit unstable on my projector (7 kg). Not that it is going to move from its position. It just shakes with the slightest movement. It even had some plastic wheels that I had to remove to stabilize it a little more. If you have a very heavy projector, you might need to get something else.
