Bought one of these cheesy things on Ebay. The dial has two checker flags with the word Sports above the trip meter. The dial is graduated in MPH with a wheel RPM scale. The innards is full of plastic gears. Construction is poor at best. The one I received was defective. The trip meter works but the speedometer pointer never moves. The rotating magnetic coupling jumps up and down when the spindle turned. But hey,WTH. You can't expect perfection for 16 dollars and free shipping, can you? I don't recommend this particular one. Don't know about others.
