Good budget holder with small weaknesses

I bought this bracket to a 42 "television from LG to be mounted on the wall by the same manufacturer I have already bought a fixed bracket and mounted, so I knew more or less what to expect me first about the benefits..:
- The part is really stable, but also quite difficult.
- Mounted on the wall and fully extended wobbles nothing, despite about 15kg heavy television with 45cm lever.
- Installation is relatively simple and well described in the manual.
- There lieth a bunch of assembly materials case.
- On price and function there's really nothing to complain about.
Now the neutral points:
- I already knew that to mount a 13mm nut is required (from the previous model). Who does not know in the rain.
- The 42er was before at the other holder. The support rails are not compatible (although they are almost the same, only a few millimeters difference), so I had to ummontieren. But it was a matter of a few minutes.
The Weaknesses:
- The part is really hard. In addition, the holes in the mounting plate agree not agree with those in the mounting plate for the TV. That has to draw the drill holes to the bracket extend and hold the bracket to the wall. For an individual not easy. It would be nice if at least beiläge a drilling template.
- To install the bolts / nuts for the determination of support rails, you need a pair of pliers. With your fingers you do not get through the Löcher.gefummelt.
- Joints are easy to stiff, the usefulness of the pivoting range. In the manual is not described how these are to be solved.
- My TV has a 400x400 VESA spacing. This means that the brackets fit into the retaining plate. Unfortunately, the mounting plate on the sides no noses (unlike my other Ricoo bracket). Ie there is always the risk (even if you use the pivot function) that the support rails slip sideways from the retaining plate. Even hooking the TV in the retaining plate is made more difficult.
All in all the whining at a high level. One star deduction is justified I think, but certainly not more. It would be nice if Ricoo not only negative reactions gives comments, but also reacts with positive suggestions for improvement.
