Wrong instructions, no leveling or tilting functions, but at price point for basic product that can move screen up and down.Base provided is different from instructions, they provide 2 feet to attach to motor base. TV bracket diagram is wrong but you can figure out how to put it together but there is no leveling adjustment so you may need to not tighten until you can level your TV. Limited screws for TV attachment were provided so you will need to get them separately. You will also need bracing to the wall or to cut the runner. If you cut the runner clearance from the TV to the wall is limited so make sure TV connections are not limiting. For a experienced installer.
