Easy install, but tv went crooked when it was extended towards limit of extension. It was very noticeable when arm was to the right, but not when it was repositioned towards the left. Too much play in the extension joints. Installed this for my dad and next day he said plastic piece had broken off (Turned out to be the cheap plastic wire-run that never quite fit on right anyways). Went out and bought one from Sams club knowing I could return it if it also had extension/tilt problems. Well the one from Sams Club (Omni Basic Series) was just fantastic and it came with two STEEL wire-run holders even though it is a bit shorter on the extension than this wall mount.
