Review on Monoprice Flush Type 3.5mm Stereo Keystone Jack (White) - Improved SEO! by Michael Lucas

The connection in these blocks is extremely strong. I've bought a few over the past year and they've all had a very good, very solid connection. You never have to worry about cables falling out in the wall. although I still used the tape tab just to be sure and prevent anything else from accidentally touching the outer surface. I've used them for both the stereo IR emitter lines and the mono 12V trigger lines and they worked fine in both applications.
