10 Foot USB 2.0 Type A to Type B Male to Male Cable with Ferrite Beadstar rating 5Paul E. SchoenOctober 4, 2010I measured the shield resistance from shell to shell and found 0.2 ohms before flexing the connector and 0.1 ohms afterward. This easily meets the USB spec of 0.6 ohms but the resistance change indicates possible long term reliability problems.Shield integrity is probably not critical for most applications, and this cable seems to be very well made and is an incredibly good bargain for a cable with gold flashed connectors and a ferrite bead.
