(5 stars) Perfect for Network Device Configuration

By:
Bought this way back in 2013 for use with my college computer program which involved a lot of network device configuration (primarily with Cisco switches, routers, and firewalls). Never had an issue with this adapter functioning as intended. It worked reliably and it's really durable considering I've had it knotted in a ball, and stored in a tight coil but it still works. It's almost 4 years later and I have no concerns about this thing lasting me a decade or above. Never did use the parallel portion. If there's any complaint I have, it's that it feels a little cheap since it's just plastic, and it looks very plain with just the grey. Making it like a black matte plastic like the many video adapters, and adding the company logo would be a nice change.
