The WH is to work with a lot of TV. Screws are available for each television in. They can be mounted with 17mm or 40mm distance from wall. I opted for 40mm, because going at my TV many connections backwards. With a mask you can see the holes, for all common VESA standards, easily bring to the wall and losbohren. 100% it does not have to be horizontal, since one the TV still can straighten when it hangs. Long bolts and quality Hilti anchors, for attachment to the wall, are included. There have 4 holes are drilled (for each bracket 2). If you have both brackets to the wall, the small particles can be fixed fast on TV.
Then unfortunately the hanging was not so straightforward. Because if you only 2mm next pierced what may soon happen to anyone who does not support goes 1: 1 pure. You mus then only time reinhängen the first page and then fumble the TV back and forth (you can move the TV so later), to the other side then fit exactly. And all this on a few centimeters between the wall and TV. Here the holes on the WH could have been a bit bigger.
After the TV hanging on the wall, one arrives at the rearward unions ran very well. The TV does pull down etas forward. One of the lower spacer has a small strap that can be folded down so that the TV stays in this position. Now you get quite comfortably to the terminals.
Qualitättiv are the parts supplied definitely quality. Whether that justifies the high price, everyone must decide for themselves.
