it is perfect. I use it speedometer + mode mapping. - The grip is easy, the fionctionnalités are not hard to understand, as it is not in ultra-sophisticated models (such as 500, etc.) - He finds the GPS rather quickly (except the first time but now he has to remember the last position) GPS accuracy is very good, much better than the smartphone I was using before. the plugin allows to directly load circuits on the sites (not just myGarmin, I use Endomondo for me). fixation is strong and holds well especially when you start sending timber 'mountain bike (there were several sizes of elastic to fit the handlebars). - I do not use the 'show me the way' available, because I have never the occasion. indicated as waterproof, meaning that in case of heavy rain it will not deteriorate. The 'cap' that closes the USB connection is located below, away. - The battery life is good, 14 hours, I could do more outputs (3 for now) 2-3h each bike without problems; I did not go after the battery again.
it's perfect for those who want a GPS meter without display card; I do not regret my purchase.
