met for little money exactly the purpose

I have already assembled several bird mounts between 150 and 250 EUR).

Conclusion:
The difference is only visually - but this of course can be quite an argument, because with the extended television can be the admittedly ugly baseplate look good.
an integrated (but hakelige) cable management, like the bird, although also missing. But with a couple of strategically attached cable ties easy to improvise.

the mitt supplied dowels and screws are absolutely appropriate and well-sized.
However, you should have a ratchet at hand because the screws are really hard to screw when the holes are not just knocked out.

Bottom line, a technically convincing product with weaknesses in optics.
but for the price a strong buy recommendation
