No issues with order or delivery. Product bought to be used with wristband and Marware Sportsuit Sensor+ case. I had lost original sensor that came with wristband and which was taped to a non Nike running shoe. Linking new sensor to wristband was simple; just hold down side button on Wristband in proximaty of sensor. Despite what Nike say the sensor works perfectly in the case attached to laces of non Nike shoe. First upload failed; needed firmware update, but probably coincidental.
