The holder is very stable. With the supplied (various lengths) screws I could fix the TV (Samsung ES7090) without problems. For attachment to the wall four holes are provided. For security reasons I took 10er dowels. Unfortunately missing in my delivery of the cable holder and the sheath of the second cable holder. This was noticed only after the fastening on the wall. For the ping-pong game between distributor and supplier (suddenly Amazon is the supplier) and Amazon (unfortunately can not send items only fully return) I deducted a star.
