I need to add a little extra length to the network cables I have connected, and these worked well. The only issue that I've had so far is that you have to ensure the ends stay fully seated into the coupler. If the cable is pulled on, the ends pull out of the coupler slightly, and the connection can be lost. If the couple is placed somewhere that will not need to be moved, won't get kicked, etc, these work as advertised. For my needs, they worked.
