Review on UGREEN Coupler Ethernet Extender Adapter Computer Accessories & Peripherals and Cables & Interconnects by John Destruction

I bought 3 of these kits (30 total) to expand multiple sliding POE cameras. As long as the devices maintain a signal, the cables will continue to fall out of the connectors. The mechanism they designed to hold the clamp is faulty and doesn't work. The cables I use are subjected to no stress other than gravity and are laid horizontally in a false ceiling. And yet, when I lose connection, I keep finding that the cables have fallen out. Very disappointed with this product.
