Verry disappointed going on previous reviews .this was going to be simple to hang my TV on wall .base plate screwed to timber studs in structure .tilt hangers fixed to back of TV after assembly of locking mechanism.but when lifting TV to mate both the top hooks don't fit over the base plate . removal of all from TV and wall had to file a couple of mm of the hooks to allow clearance to pass over the wallplateand then lower into hook resting place.then the issue of the security screws at bottom position is way too close to wall when in situe and clearly not enough stability in 2-3mm thread to aid tightening in an already confined space .I'm an in joinery trade and have loads of experience in this and have tools readily available.this with most definitely cause other not so diy savvy customers concerns
