The mounts are extremely well made for the price and work very well. They have foam rubber pads on both clamp sides and bottom of the mount as to not scratch speakers and to nicely grab the speaker. All parts fit well and once all tightened, they are very solid. I only have a few minute gripes with them, first is the carriage bolt provided uses a plastic washer to attach the bottom plate to the wall bracket and cannot be tightened after a speaker is installed (The bolt just spins since the washer stopped the carriage bolt from working properly). Second, as other reviews mentioned, the plastic cover to hide the screws and wall mount doesn't fit very well and sit a few cm from the wall. Thirdly, this has nothing to do with the functionality of the mounts but rather the appearance. The "Prime Cables" logo is silk screened on the arm in white which is not shown in the photos anywhere and just makes them look physically unappealing as I am want the arms to just disappear. A little bit of acetone made quick work of removing this. Again don't get me wrong these are great speaker mounts, just a few things to note.

Solid speaker stands will be great for our outdoor gazebo.

It’s Ok.

Have not used it, but arrived quickly.

Hefty speaker stand, haven't set up yet but I don't picture any issues

They hold my studio monitors (Kali LP6 v2) very well. My only complaint is the flimsy plastic washer used with the bolt for the part that makes the speaker clamp tilt up or down. I only broke it on the right clamp. It's really easy to break by barely overtightening the bolt. It still functional but I have to untight the bolt to change the tilt angle and retight it back to hold in place.
