Two things appealed to me about the Coros Dura bike computer: it's price and the relative ease other reviewers gave for ease-of-use. Price is definitely favorable compared to other GPS computers but as for ease-of-use, I'm less sure. You will need to use the app to do most things, then sync the app on your phone with the Dura...that part is easy. Less so, is wading through the myriad of features you will likely not use to do what for me is the essential: mapping rides, importing routes and measuring distance, elevation gains and losses etc. I've had it a couple of months at this point and I've imported routes and used the routes for riding but I am by no means masterful at using it - I suspect it will take a more concerted effort yet. Overall, great GPS, just wish there were a stripped down feature for easier day-to-day use for those not training for a triathlon and don't need splits, laps etc.
Went on a 5.5 hour ride, screen set to bright, navigating the whole time. Battery used up 8% and charged back up 3.8%, for a net use of 4.2%. I've had this for two months now and I'm sure one of these days I have to charge it. Any day now.
