### ⭐⭐⭐⭐⭐ Good Solid Performer
*by M***I on 3 September 2025*

I’m using this to connect my AP to a faster switch (via Poe injector) as I don’t have any spare 2.5g ports. Works really well & delivers the speeds required with no issues. I’ve had no connection issues, really good value for getting the job done.
