good value but my Garmin 800 was better
I had a Garmin 800 to which I'm comparing this V650. The V650 has Excellent battery life and visibility. Easy to use. Very good features for the money. However, The screen is not sensitive to your finger, and while riding this difficult to change your views. Sometimes I change the due by mistake and can't get back to my homepage. Mapping function does not work as well. When you come home and download the data onto your computer the route you ride obscures the names of the streets. Missing features the Garmin has is temperature and angle of ascent which probably was not very accurate anyway on the Garmin. Easy to hook up and download information onto your home computer. I haven't used cadence or heart rate monitor.
Overall I'm very happy with the purchase.
