Great Product!

Works very well with Cisco switch and UCS mini chassis.

Using with unifi dream machine se and older generation 24 port unifi Poe switch. Works as expected.

Bought several of these to connect Ubiquiti switches to each other, as well as servers to the switches. No issues observed after nearly a year of usage; for the price - cant go wrong with these DACs!
