Our 6ft  USB Cables are specifically selected for use with biofeedback devices.  However, in some cases 6ft is not the perfect length for your office space.  Please Note: By using this 15Ft cable, you are potentially lessening accuracy with your biofeedback equipment.  We suggest using 6Ft length USB cables for Biofeedback.
