Great Product!

Seems to b of decent build quality. A little thinner than Cisco-branded DACs, but a bit more flexible. Didn't test throughput extensively, but no complaints moving large amounts of data between devices. Can confim it works perfectly fine on 10G SFP+ ports on several Cisco devices, as well as a Mellanox 10/25G NIC. The fact you can order these at a multitude of lengths, and significantly cheaper--unless there's compatibility issues with certain equipment, or you have a service agreement that forbids it, I don't see a caveat.

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.

Worked as soon as contacted to my switch and HPE server. None of the transceivers that HPE sent to me worked except this one. Really deserves five stars
