Just installed my 42" Plasma in our bedroom, and here's my take:
This is actually a high-quality, very sturdy mount. When I took it out of the box, I was pleasantly surprised.
Now, here is the REST of the story...
The directions that come with this kit are mediocre at best. The pictures are vague, and only after wrangling with this pile of metal did I figure out how this thing is supposed to be assembled. First of all, the included drywall anchors are NOT drywall anchors at all -- they are masonry mollies, and won't work with standard residential drywall. Thanks for telling me before I put 4 gigantic holes in my wall, Cheetah!
So if you're using this in your home, here's what you need to do: 1. Assemble the rack on the floor/table/bed/whatever, and make sure it is square. 2. Find the wall studs, and mark them lightly with a pencil. 3. Hold the mount up on the wall where you want it, and the make sure the holes (not the "obvious" 4 holes) align with the stud marks. Adjust as necessary. 3. Level the mount horizontally, and drill pilot holes into the studs (make sure you are on-center!) and drill THROUGH the appropriate holes. 4. Use the included lag bolts to affix the assembled rack to the wall with an impact driver. 5. Attach the vertical bars to the TV, and then hook them on the installed rack. 6. Slide the mounted TV left/right, and tighten the clamps once the preferred angle is achieved. 7. Carefully screw the lower set screws into place (which hold the TV in place in the event that it gets bumped). PHEW! It took some elbow grease, and some joint compound to patch the errant holes, but once I figured this thing out, it actually made sense. I'd love to re-write the instruction booklet for these guys, but now that this thing is on the wall, it's STAYING there! I was just at <a commercial retailer> today, and they have the EXACT same mount, under a different brand name, for $140.00. Had I purchased their product, I'm sure this review would be a tad more negatively biased.
There is also extra hardware included in this package, which I found distracting, and made me wonder if I was misreading the instructions. From reading other reviews, all I can say is that I empathize with those who struggled with this kit.
The bottom line: It works, it's sturdy, it's flexible. The instructions are lacking, which leads to frustration, but your average DYI person can pretty easily figure this out. Would I buy it again? Yes. In fact, I AM going to be buying another one real soon for the basement setup.
