Review on Dinggsun RJ45 Coupler 10 Pack - Blue Ethernet Extender Connector for Cat7 Cat6 Cat5e Cables - Female to Female Adapter by Kyle Tran

I know there is something wrong with stuff like this from these companies on Revain and mine clearly failed. Just didn't work right out of the box. I checked all cables separately, all devices work. Place the connector between the two cables. Nothing. So clearly not worth the money (or time now that I still need a fix and have to wait a few more days!). I probably should have spent more and gone with Ugreen as I have used their other products and had no problems.
