I've been wanting one for awhile now, I got it at walmart on sale for 10$ or so. Just installed it and tried it out. Went 2.23 miles at a maximum speed of 12 MPH in 8 Mins 30 Sec. Was going to go longer but when I reached my destination (the city library) it was closed first off, so I decided just to head home.
It's really cool though, this ones pretty small and simple. About the size of a square wrist watch, about 1 CM thick. Large MPH digits on top, small Odo digits w/ auto keeping timer at bottom.
Anyone have a really cool one of these things? like a really expensive one or something? I'm intrested in seeing some.
