Anyone else have these? I recently got some and they're awesome. They have sensors that record vertical, quickness, and "nikefuel". For example, my stats so far are: 32 inch vertical, 8 steps/second, and 7000 "nikefuel" Post your Nike username here and I'll add you.
i haven't tried them, mainly because they measure things like 8 steps per second and nikefuel, and both sound silly.
Steps per second is how quick you are, and nikefuel is kind of stupid but it shows how hard you hustled.
