I purchased these to mount 4 infinity speakers in my living room for surround sound. The speakers weigh around 8lbs each and these mounts support them with no problem. Installation is pretty straight forward, however I used my own fasteners so I can't comment on those included. The mounts can be adjusted to be aimed in a multitude of directions however I would recommend adjusting them before securing them to the wall. I used one side of the mount to secure directly to the stud so I didn't have to use the other side or mount to drywall. They are very sturdy and look professional and I would definitely buy again.
