These adapters have been amazing for our workplace. We work across Macs, PCs, and Bootcamped machines regularly, and these adapters work flawlessly with all of them. Even for older computers drivers are easy to find and we can still use them. They are fast and highly reliable, we run live show control systems through them on a regular basis and have no issues with MIDI, DMX, ArtNet, or anything else.
It work as it should with the stated specs. "Would recommend this to a friend." *thumbs up*
PROS: Almost* plug and play, I mentioned almost because you need to install the driver from the CD first. I didn't tried hooking it up with the existing ethernet connection (to automatically fetch the necessary driver.)
CONS: A bit on the bulky side but that is okay for me.
