    Makes a long ethernet cable out of two shorter ones. True, you can't pull on the loose ends as much as on a single cable, but I don't do that often and this isn't going in an out of the way place. So, works fine.

    Perfect or connecting a second short CAT5e cable to an existing run to make up a few additional feet between printer behind my desk in the corner of my office to my computer, and saved having to buy an additional longer cable.

    When your cat cables aren't the length you desire, this product is an excellent solution. Just plug one cat cable into each end of this coupler and it's just like having one extra long cable. I definitely recommend this product.

    Needed to hardwire my PS4 from another room and had to connect a 10 foot LAN line to my 25 foot one. Worked perfectly. No issues with losing any speed. Only caution is it does not say it is compatible for Cat 6.

    This worked just as I had hoped. I connected two shorter ethernet cables in order to be able to wire into my router directly for better speed when working from home. Would recommend.

    I needed a little more cable length and I already had two cables. This allowed me to join the cables and get that length. It works great and saved the expense of buying longer cables.

    After buying a 50' ethernet cable and realizing it was still too short, I just bought one of these and using an existing 25' cable completed installation of the security camera I was in the process of installing. Works great!
