Installed it myself only and took me about 3 hours to finish. Not easy to do it by myself because I had to take care of the TV. Hold perfectly for my 55 inch TV. But when move it I can see the TV shaking a bit... The structure to connect the TV (upper part) is simple but is stable by design. The vulnerable part is the lower end, where only two screws are holding the entire stand plus the TV. Tightened the screws as hard as I can. I don't know how to make it fixed on the ground using the brake. I tried but it kept loose.
