I have about a 100 foot Category 5 run and it was 3 feet shorter to get to my router so I used this coupler and a small cable to make up the difference. I connected my computer to the other end and ran speedtest (image of results provided). I have gigabit service and see about the same speed on the router (wired). I am very happy with this connection as there was no loss of speed (up to 750+ Mbit/s). I also tried a UGREEN CAT6 ethernet extension cable and got no signal. No communication with UGREEN cable. Buy this clutch instead, it works much better.
