    Got the job done , allowed them (DirecTV) for first time in 10+ years to register/establish an internet connection to this specific DVR after losing home tel line to another office device 10 years ago. Able to connect home router to my DirecTV HD DVR using this handy coupler x 3, and allow easy browsing of their movie library, pick my favorite adventure/drama/war movies to watch. Needed 3 of these couplers to bridge the gap from TV area to router room in basement and the price for each coupler was reasonably priced. The electronics person was extremely helpful in finding this coupler and getting the needed footage of cat cabling to make all this happen.

    Needed to extend my Ethernet and this worked perfectly. I installed security cameras and didn’t know if these did POE ( Power Over Ethernet ) the online description doesn’t say that but in store the package says it does. Just in case someone else is looking like I was.

    You just never know when you will need one, and when you do, everyone, especially you, is glad you had them. Couples two Ethernet cables together to give you their combined length. (Cables sold separately or you must have your own.) Connect devices that out of range of WiFi via an Ethernet cable or when visitors come and the kids need more speed online to enjoy faster multi player games. Just use them to click in the Cat 5 cables and off they go! Beyond clicking in the cables, no set up required, they are just a pass through of the signal in the cable literally making it child's play to use.

    This little device is perfect for extending an existing ethernet run. I have pre-wired CAT5 to my living room (with no jack) and after rearranging my furniture needed a little more length. This purchase allowed me to add on a short cable with the female to female adapter. There was no setup and no loss of quality or speed. It works great.

    Not a lot to say about this little guy. It did exactly what we needed it to. We need 50 feet of cable but only had two 25ft. Was able to run to Best Buy and pick on up. It saved us a ton of money as we run a medical facility and needed to move a piece of equipment from being damaged due to a leak.

    This was useful for my situation in which I had two cables and used this coupler to essentially create a 50 ft long cable to move my media box to a different room temporarily. No streaming issues at all. It is compatible with cat 6 cat 5e cables coupled together, whichbis what I had

    It does the job. It was much cheaper to buy a connector than a longer ethernet cable. It's made pretty sturdy, because I've dropped heavy things on it and it didn't break. A cost saver for sure

    This is designed to connect two LAN cables to make a longer one. These work great when you need to extend the cable that is in and inaccessible location. It saved me from going into the attic and outside in the weather and replacing the existing cables with longer ones, by simply clipping this between the old and the new cable I was able to relocate my server and security camera system.

    I needed to extend the length of an internet connection cable. This device allowed me to add to the length without a complete rewire or splicing. It is inexpensive, easy to use, and worked flawlessly.

    I bought 2-50ft Cat-5' Enternet Cables. One for both Bedrooms. First bedroom ran it down to the basement then back up to the Wifi Router that is position in the livingroom. Master Bedroom I did samething but I was like 15 ft too short. Thanks to a Best Buy Employee that show me this product instead of just selling me a 75ft cable. Snice I already had my 50ft cable ran & hidden. I just used the Coupler adding a 25ft cable that already had then my job was done. So I saved alot of money and alot of Precious time. Great Product, Thank you blue shirt guy lol
