Remove TV again ????

So from the wall bracket I am not at all convinced because they ...
1) ... was not right for my Samsung UE40C6000 because he is just too big (although he actually only 40 inches, that is, it would fit)
2) The screws for attaching to the wall right there are, where the television hangs afterwards (ie, when the screws depends already with the 1st part of the wall bracket and the wall, and you now want to mount the TV disturb the screw heads)
3) Those who have tried to get to now his TV from the wall ??? I make it just does not, and is not due to the anti-theft !! There can be no lifting and no pulling, the thing depends bombproof on the wall.
That would actually be an advantage but not safe with me.
4) Because one bad gets the TV from the wall, each additional plug connected to the TV to an embarrassment because you did not come back the TV with your fingers and you have therefore always depend on him ...
So I'm dissatisfied with the part
