Does what it's supposed to, but there's some hardware variation.
The plate is fine, well made and sturdy. The hole are right where they should be. My TV had only the smallest receiving holes so the hardware supplied was not adequate for my needs. A quick trip to the hardware store and I'm good.
Worked well. It came with a variety of spacers and nuts and bolts. I probably used it just a bit differently than intended and had to buy a few other nuts and bolts. It would be nice if it were painted black, as the TV mount is black.
Used this adapter plate to mount a new Sony 43-inch on an older adapter arm. The original TV used 200 x 200, the new Sony is drilled and tapped for M6 bolts in a 200 tall by 100 wide pattern.. Along with this plated I used M6 bolts, lock washers, and nuts from Home Depot -- and eight 1/4-inch plastic standoffs from Amazon. You need the standoff to provide clearance for the boltheads.
The adapter plate is very solid. I also purchased a "universal" adapter plate from another vendor but I couldn't use it. it was not square, more of a butterfly, and the holes were too big to provide a secure mount. This one worked right out of the box in my application..
