I got this so I could move a 60" TV around in my home gym. It works well, the casters roll the unit very smoothly and lock in place. Assembly experience could have been better. The instructions are pretty basic, but it's pretty straightforward. There are a number of different mounting positions and hardware provided, but the combination I needed for proper positioning couldn't be done without extra work and hardware. Trip to the hardware store was required to get longer bolts, and had to drill some holes in the metal because of where my TV's optical adapter for the sound bar and the power adapter plugged in. There's nothing to keep the TV in place horizontally except a small lip of metal, so that required some extra hardware to address.Once assembled, though, it's very solid. It comes with three shelves - all are optional though if you don't need them. Very easy to move around and the locking wheels are well made. I can't speak to the ease of adjusting the height of the TV because I haven't done it after the initial mounting, but that option is there - I'd use two people to do it, though.
