I was looking for a GPS bike computer with a longer battery life because I sometimes had to do longer trips of more than 300 miles. My old Garmin only runs about 10+ hours and it really drove me crazy when it broke down during a trip. I wasn't aware of Shanren until I came across a Cycling Weekly post about this GPS. So I decided to give it a try. I only fully charged it once and then did a few long test drives. Finally, I am very impressed with the result - only 1770 km and 96.6 hours as I counted by hand! That's great. I also like the design of the headlights and signal lights. While the headlight isn't as bright as I'd imagined, it's perfectly adequate for the occasional night ride and is just really handy - no need to take another light with you. I also bought Shanren's EKG heart rate monitor, works great with Discovery Pro and love the additional EKG output in the Shanren app! I'm a happy customer.
