I see they are updating their site. The link I posted no longer works. Its 5" long. Heres another link to see what it looks like. Note the one shown in that pic does have the 4 shift technology. The one I have has more features. It records each shift point for each gear, tells you your reaction time from when lite came on till when you throw the shift. Has a staging rpm feature and records your rpm at the finish line.
