I bought my Edge 800 in 2010, still use it. We have 2 of them on the tandem. Never had a problem with them, other than running out of battery at ~10 hours. I have a battery pack I use if it's going to be longer than that. I also upload everything. I really like the ability to follow a route and also to see the route on the screen. Only thing is that I wish the screen were larger, but I could upgrade and get that.
