This is now the holder 3 that I have and now I'm finally satisfied. You can adjust the projector without the wobbles nicely the whole bracket. To attach I hergenommen 10 dowels as 2 holes for attaching and with 8 anchor is simply not enough. But the bolt circle diameter was too small for my Mitsubishi HC6500. So I had a bit of improvising. My projector has only 3 instead of 4 threads for fastening. I then simply connected to the other arm 4 with 3 arm and then everything was fine. A point I have withdrawn, as these brackets are intended for smaller projector. But Full HD beamer are now times much larger.
Conclusion: Only holders buy with universal joint, then must then do not fret, what you have bought again.
