Great item
Works as it’s supposed to, super simple to use, mainly used with cat 6

If you have to use a CAT-5 coupler use this one.
Used one of these CAT-5 couplers outside my house to run CAT-5 to a detached one car garage. Installed this coupler in-side the customer side of the plastic housing "de-mark" that the cable company has on the outside of most houses. This is not rated as weather proof but we are getting a full 1 Ghz ethernet speed at the end of about a 70 ft run and no issues. This is a much heavier duty coupler then some I have had in the past. I would expect that this one ensures the best possible connection when you have to use a coupler. I will be the first to admit that with couplers you are asking for trouble. In this case the run was in buried conduit and would have been impossible to re-pull. I was glad I planned ahead and had the run pulled when the garage was built.

Worked better than I though it would
I needed an cat 6 ether net cable length that was not common, so I got theses instead. I was able to connect two ether net cable to get the length I need by using these connectors. I tell you what, it worked better than I expected. I ran a speed test on the cable before using the connector and after I finish running the cable with the connectors. I only seen between 5 to 8 mbps drop. i have been running them for a few months now and they are still going strong.

Great value - good product.
Work well without any issues. Construction is good. I had to double check the connectors when inserting them as a little care is needed to make sure the clip clicks in to place. This is not a big issue, however.

Using several. All working great.
I am using 3 of these to extend a single Cat5 run. That's definitely not best practice, but these really saved me a lot of effort. A house had Cat5 for phone wiring and I repurposed it for networking. In order to avoid pulling a new wire, which would have been a huge ordeal, I terminated the existing Cat5 runs with RJ45 connectors and used this product to splice them into a long run through a house. I was hoping for a gigabit connection in the end but expected to be content with a 100M link. To my surprise, I got a reliable gigabit link.

Each connector tested well
I have a 2.5 story home using a Synology MESH network, with a RT-2600 as the primary router upstairs in a closet and a MR2200 downstairs in the living area setup as a Wi-Fi access point. ~40' of in-wall Cat-6 Ethernet is connected between both devices running through two unmanaged switches. Running a throughput test from the RT2600 router's builtin application provides an average speed of ~ 915Mbps, both directions, for all five of these extender adapters when connected at the MR2200 WAN port connection using a short extender cable; this is the same speed as without a UGREEN adapter installed.

Chunky, solid, effective
I ran some flat Ethernet wire through my house (but not inside the walls; not ready for that much work) and used these couplers to connect cables together. They work perfectly, they have a simple boxy shape, they’re solid as a rock, and they attach nicely to a wall with a Command strip.

fixed my problem
Works as advertised tested speeds with wires from router to computer and then with router wire this adapter and then wire to computer. Both speeds are close to even. When I needed a connecter to extend my wire to another room and couldn't run a new wire this works as should and hides nicely. Not to big and could be a little smaller but for quality and price I'll deal with it. Also the 5 pack just in case I need for other room for the price of 5 really cheap instead of buying just one. Put a picture up for other buyers to see. -Dan

家庭内でノートパソコン(3台)やデスクトップパソコン(1台)を取り換え使うのでLANケーブルの抜き差しが多い。ケーブルの先端のコネクター部分の摩耗が気がかりになり、転ばぬ先の杖でケーブル中継アダプターを間に入れた。小さなサイズよりもこの大きさが目立ち、卓上において安心。ケーブルの抜き差しも楽だ。アダプターからパソコンへの接続にはElecomの50センチとダイソーの1mを消耗品的に使っている。

Para hacer prolongaciones sin pérdida de velocidad. Un producto que se nota bien hecho y a un precio muy ajustado. Después de dos meses de uso no he perdido nada de velocidad y siguen funcionando perfectos

Entrega perfecta según condiciones prime. He usado el producto para conectar dos tramos de cable cat6, uno de 30 metros con otro de 15 y se mantiene el 100% de señal. Tengo fibra de 300 Megabits/segundo y después del empalem con este producto me llegan 315. Los materiales parecen resistentes. Muy recomendable.

Love these, saves buying a new run of cable when I have a few different lengths that were either just too long or too short. No signal loss detected, everything is running perfectly. Just stick either end of your network cables in to the coupler and away you go. The construction feels solid and reliable. I will definitely buy again should I have need.
