You may have noticed the text above says that "...two cannot be used side by side in the same wall plate". I easily mounted two of these side by side in the same four jack wall plate with room to spare between them. I have pics to prove it, but don't see a way to post them in my review.
I installed quite a few of those and they all have been working great, from the first install, no failures, everything working great on first try. If there is one thing to improve on it is the little plastic caps that go over the "teeth" after the cable is installed - they don't always seem to install snuggly or they don't feel very secure. The operation of the jack does not depend on those caps, but it sure would be nice if a better locking system could e designed to better hold them in place.
