Review on Full Motion TV Wall Mount Bracket Swivel Articulating for 50-90 inch LCD, OLED 4K Flat Curved TV - 29 Inch Long Extension Arm, 24 Inch Studs, Max VESA 800x400mm, 154 lbs Capacity by Pipishell by Brandon Boones

These mounts are really good for freedom of movement and the ability to hold a heavy load or a large screen. I have four of these at home. They come with all the hardware including a good selection of hardware to attach most screens to the mount. The arms are long enough to rotate my entire 70 inch screen 180 degrees. The mounting plate on the wall allows you to install the centers of the racks on 16 or 24 inches. Side adjustment based on the width of the VESA mount on the screen The mount knobs on what attaches to the screen have a great locking system on each arm that really secures the screen to the horizontal mounts, in other words the screen will never just fall off or move My only complaint is that I wish the mounting arms were 600mm long and not limited to 400mm. The downside is that there is a hex screw on the mounting head plate that blocks the screen axis. It works great BUT if you overtighten anyway it will break and render the entire mount unusable. I actually had two fasteners that failed during installation, seriously, just tighten that screw. Luckily the manufacturer sent me new headstocks from China in less than ten days to fix the mount. Customer service was on site, usually responded to me in less than 6 hours, and parts were dispatched within just 24 hours of the request. They were sent by DHL and arrived in two packages, one in 8 days and the other in 10 dozen.
