make sure you hit a stud
just used these to hang my ~14 pound speakers. the first one i put straight into a stud, and had absolutely no problems with it. the second one i tried putting on drywall with the included anchor, and it was not holding it well. i ended up ripping that one off the wall and moving it to a less ideal location over a stud. if they included better anchors with the mount, or had better advice on when to use them in drywall in the instructions, i would definitely give this 5 stars. once it is up on the wall good and tight, it is a great mount.

will not support the weight they claim to
i was excited to find a set of mounts that claimed to hold the weight of my speakers. but while they do hang from the wall, they are supposd to be adjustable so you can aim the speakers. well the teeth don't bite into the plastic ball good enough to hold the weight they claim. so the speakers end up sliding down to the lowest aiming position until the stud bottoms out in the wall mounted socket. it worked out perfectly for me since that's where i needed them anyway, but you don't have a choice if you go with a heavy speaker. other than that they are pretty sturdy. the price was decent compared to others. and they do look pretty nice.

Hangs 'em @ looks good!
Having a pair of Bose bookshelf speakers and no bookshelf in the area that they would produce the best sound, the Omnimount Speaker mounts proved to be perfect. Proper speaker placement and the sturdy wall mount provided by the 20 pound rated,( the speakers weigh 11 pounds!), Omnimounts allowed speaker placement for optimal performance and a clean looking set up. I will be ordering more for mounting monitors in my music studio, and looking forward to any other applications in the future. Sturdy, well built and a quality product. Thank you Omnimount!

Weight rating is misleading
I have used the Omnimounts twice: the system rated for 20 pounds, with 16-pound speakers; and the system rated for 10 pounds, with 7-pound speakers. In both cases, I tightened the ball joint as much as possible and the mounts still wouldn't hold the speaker in the desired position. In addition, the drywall mounts on the 10.0 failed completely, and the instructions are vague and not terribly helpful. Finally, the location of the Allen fastener for tightening the ball joint is all but inaccessible. I can't recommend this system.

Good idea, but...
They look good. They do what they're supposed to.

But it is a little difficult to get to the allen screw that holds the speaker position solid. Which is important with 15 pound speakers that you don't want just leaning into the wall.

Also a hex type wall mount screw would be better for mounting to it to the wall, (I happened to have some around) as the big phillips heads supplied are tough to get into a stud without stripping the head. Even with a good predrill.

These items aside they do work well and fit our needs perfectly as they are slick looking and very easy to hide.
