Please note, the entirely smooth side of the biothane (white or dark brown strap) should always be facing forward as pictured with the grooves facing FORWARD to fit properly. This ensures your Fi endlinks are properly inserted into the Fi GPS tracker and does not cause damage to the endlinks by inserting the notches backwards.
