Yeah i'm definately happy with them, i wanted something that looked different to normal but still had good features with them. There as accurate as u set them up to be really, to calibrate the speedo u just drive a measured mile and your set to go. If u have a custom fuel tank u can set them up for that aswell. They have some pretty decent features on them such as trip distance, odometer, service, hours, high rpm, rpm warning, high speed, 1/4 mile time, 0-100 (0-60 for u i guess). There are a few more but can't think what they are.
