Very well fixed in plasterboard with Moly since there are plenty of holes for screws to full ;-) Of course, the integrated level is useless but then nothing! The different mounting screws on TV, even too long, have plastic spacers cutting the cutter to properly secure the plate without using hacksaw or buy new screws! Once in place, everything is solid and TV inclines slightly if needed without being 3 km from the wall, which is quite elegant. Good value for money.
