Unfortunately absolutely no holding function

The camera base fits in wonderfully, and the camera is also very stable through the bracket.
However, the "locking" of the bracket is so fragile and spongy that secure attachment of the bracket to a TV is hardly possible. A slight nudge is enough to let the sail holder.
A recent Samsung TV (relatively thin) and a very old Toshiba TV (about 4 cm thick) were tested with the holder. With the aid of a power strip mounting is possible, however.

Very good idea, implementation absolutely deficient.
A spring in the joint would certainly tremendously help the requirements for such a holder to fulfill.
