They are easy to install. The speakers turn on immediately. They're far from finished, but they work and are hard to see. I used them on my Klipsch Atmos speakers and you had to twist them a lot to keep them in place. The location of the clamp screw and wrench behind the speaker is difficult to find so that they are tight enough to hold heavier speakers. They are installed but not used. Instead, I used speaker stands.
