yeah... just picked one of these up the other day when i saw it at wally world for 10 bucks... too cheap to pass up. Damn if those little chineese kids didnt do a kickass job, the thing is so awesome. i put in the circ. of my tire in mm so you know its gotta be accurate? right?
i definitely consider this to be absolutely correct for speed. its so nice for tuning, you can use the trip timer for doing 0-30 times.. max speed, all sorts of odometer functions....
who has these? what models? what do you like about 'em? can we consider this to be 'official' speed? it has to be dead on right?
