The attachment of the two holders proved to be very easy and in hindsight to be very stable. Dowels and screws are also included. The supplied drilling template I have not needed.
Now we must try to get the TV in the bracket. Due to the small distance from the wall a real ordeal. After about 10 minutes I've also done that and the gem now hangs with minimal distance, great visual impact on the wall.
I recommend a cable duct from below into the appropriate wall color to fit. That leaves float on the TV virtually.
Definitely a strong buy recommendation.
