Cover prevents connection from clicking into place
The rubber/plastic cover on each end covers too much of the RJ45 housing. The cover sticks out and prevents the clip from clicking into place in some receptacles. Essentially, the plug isn't able to go in far enough to click the clip in place.

I was able to connect it to my switch just fine, but the device on the other end wouldn't connect. I was able to take an exacto knife to the cover and strip back enough of the cover to make it work (see photo).
Other reviews indicate the same issue. Annoying.
