That's great! A friend had one on his bike and I wanted one for my bike. Revain for the win! Not sure about the accuracy but it works. I bought the external version without the app. The dashboard is easy to set up and simply attaches to the steering wheel. Charged via USB-B cable. Haven't charged it for weeks. Cons: Can't change Celsius to Fahrenheit (couldn't figure it out) Pros: Easy to install Well built, durable Easy to read on the LCD Fast pairing when turned on Long battery life on the dash
