Not a great computer overall. The display is dim, and difficult to read in daylight, you'll need to run it with the back light all the time. Luckly the battery does seem to last. 3, 2 hour rides and only one bar down so far. Setting the time is cryptic, plus or minus whole hours from an arbitrary time zone thats not listed. Once I found the hour setting -4 ? , it was still 15 minutes off. You can't adjust the minutes. No idea why they couldn't have a regular Hr:Min setting like other devices. ThSee full review
