The screws that came with the wall brackets, unfortunately do not fit with the English UMC 1/4 "(inches) Thread the Logitech Z906 match and although my wall brackets proposed by Amazon.
Wen this error with the concerns suggest exactly, no idea. However, one should not rely on this !!
I also then ordered me here at Amazon retrospectively the appropriate screws. Here is the simple screws located in each tripod or in any camera mounts (1/4 "15mm).
Get difficult in hardware stores (I myself had no success I got the statement. "It would be an English format, nobody would grab those screws onto the bearing")
The Assembly, after I got the right screw, was quite simple. Unfortunately, the pre-drilled holes in the holder did not fit. Thanks to a fixed Dremels but quickly (hole easily expanded). If you do not have Dremel or drill is available, it will come with some force when screws because the wall brackets are made of plastic.
Conclusion: Fast delivery, per se super processed wall brackets with a light installation (if you have the appropriate screws or boxes), due to the lack of appropriate screws, despite a proposal from Amazon, I unfortunately was only 3/5 stars.
I highly recommend this wall bracket still any who wants to buy a Logitech Z906 or already has, but is thinking you equal to order with the appropriate screws!
