This really nifty, nicely designed, and modestly priced retractable cable is, like its smaller brother (3.5ft), a great way to reduce the insane tangle of wires that we all tend to end up with. Also, being real skinny and flexible, this cable can, unlike regular patch cables, make sharp turns over short distances, which often becomes necessary when components are either stacked one above the other or are right next to each other.
The only reason I can't declare it to be 'perfect' is that the connector jacks are so short (5/8") that they all but disappear into some ports (particularly our router), making them pretty hard to unclip. Also, the housing is a little bigger than we expected (1.75" x 2.5").
I haven't tried too many retractable Ethernet cables. However, on the whole the mechanism for retracting tend to break. I've had this occur on a USB retractable cable, 3.5mm audio retractable cable and a freebie Ethernet retractable cable.
I'm using these cables from Monoprice to keep my workspace neat and clean and I plug/unplug these cables frequently every week. Still working great after several months and that's why I came back to order more.
I do wish there were options for colors. It would help tremendously to be able to tell at a glance which cable is connected to what based on color. I am looking at cable identification system and hope I find one that works well with these retractable cables.
