Pros: Great support. I weigh 190 and was able to hang from it connected to 1 stud. It is a little confusing at first but a quick read of the directions and it makes complete sense. Base that connects to the projector disconnects making the process even easier.

Cons: None at all great build and I know it will never fail.

Overall Review: Works great with the viewsonic pro8200

Pros: Very stable, works exactly as it should.
Definitely universal.
Instructions were very detailed.
I was able to find a PDF version of the manual on the web.

Cons: Complicated, took me forever.
Expensive.

Overall Review: Your probably going to need two people to get this put up. Especially if your mounting it on the ceiling.
