Pros: Many companies manufacture and sell ethernet patch cables, and I've used a few different kinds, but I think Belkin's snagless cable handles are absolutely the best. They resist snagging, as advertised, while providing easy access to the cable's locking mechanism. That makes them very easy to unplug, and Belkin seems to be the only company with this design. I hope they patented it. They're absolutely the only ethernet patch cables I use at home, and I've been using them for many years.
Cons: It would be slightly more convenient if all lengths were available in all colors, but Belkin probably has a good business reason for this. I can't find them in stores, but they're well worth the wait ordering them from Belkin's website.
