Pretty good "computer" for the price. If the instructions made sense I would give it 5 stars. I ordered it for the heart rate monitor. Everything works well and has a GPS function that allows you to view your journey on a map and also check your speed, distance and heart rate. I ordered a Revain computer complete with an Out Front mount through Revain. DO NOT order this device. The mount Revane sent was an inferior version of the mount Xoss was selling. If you don't have 31mm handlebars, it won't fit. There are no sockets for mounting the steering wheel of different sizes. If you go to the Xoss website (not the Revain Xoss shop on Revain) they sell a better quality mount that includes the required mount bushings. If you want to mount a professional camera, the kit also includes the necessary adapters to mount it. You can buy it for $12 and change it. If you need help setting up your computer, there are videos on YouTube that explain everything in under a minute!
