Love my wirelss 6501. I did accidently stop my trip recording once. After that, I found how easy it was to detect if that had happened and start it again. When you have a computer, you look at it alot and not much time would go by if you accidently stopped it. It's easy to avoid anyway. I have grown to really appreciate the gear indicators and the virtual cadence feature. I have never had a single problem with it. Wish it had a backlight though.
