I ordered some other wall mounts that were poor quality and had to RMA. I bought these instead (3) and I am so glad I bought this the second time around. They are extremely simple to install, 2 holes on the top 1 on the bottom, more than enough to hold up in a drywall. I'd suggest getting some "Stub Solvers" if you are putting directly into drywall, and I'd also suggest using your own screws. The rest of the monitor mount screws work fine, just the screws/drywall stud solvers were not strong enough for my liking.
Here are a couple images of the setup I did with my monitors/the wallmounts: https://picasaweb.google.com/evillinux/MonoPriceReviewImages?feat=directlink
Overall if you are looking for a wall mount that is simple, easy to put together, doesn't require more than about 10min of work to get up on a wall and have your monitor on it, I'd highly recommend these.
PROS: Simple effective, space saving, overall great product
CONS: The screws I would suggest using your own depending on the type of wall you are putting it into.
does not fold down to 1.8 inches, min was about 3-3/4. so i had to take it all apart, cut and grind and 1/4" of metal off the arms so it would fold flat, had to sand them, paint them and one of the bolts to lock in the tilt sticks out too far to fold flat... so had to cut of the end of another small bolt i had in the garage and got it fold flat finally, level it, only to discover this mount does not articulate level, it goes all over the place from level as you move it around. not as advertised, and doesn't work well.
CONS: 3-3/4" min distance from wall, not 1.8" as indicated. due to design defects. does not stay level when you move it out.
Very poor product that does't meet up to what it is rated for. Have a 28 pound 37" Vizio LCD HDTV mounted with this product. The small allen screws to adjust the tilt portion are very light duty and well not securely hold the TV in place. It is supposed to be rated for a TV with a maximum weight of 44 pounds. Have bought a number of very good items from Monoprice over the last few years however would definitely not recommend this product.
CONS: The tilt portion is poorly constructed with light duty materials
I just purchased this mount for a 32" LED TV to put in our home gym. Went with the full motion mount so my wife could move the TV to different viewing angles while she worked out. This mount is pretty small and probably wouldn't be all that useful for larger/heavier TVs but my LED TV only weighs 8lbs so it is probably the perfect mount. Easy installation, the wall bracket only uses 3 bolts. I was able to this by myself and with a 2 year old running around trying to "help" me. The mount arm moves easily and it seems like adjusting the tilt is fairly easy, just a few allen screws for up/down motion.
Overall, for the price, this is one of the best wall mounts i've found. Easy installation, bolts/alignment holes worked flawlessly with Vizio 42". Took some adjusting to tighten down the hinge points, but otherwise a great and inexpensive product.
