Quality product, made in Japan (and Japan make very good measurement instruments) oil levels marking are at correct location tested reading and span no error. It's perfect - right on the exact temp across span 0-350 deg f. And looks correct for bike. And if you have a Harley M8 engine you must know if your getting too hot. Peace of mind for protecting an investment. -these bikes.
