I bought the Edge 605 year ago about a half and am fully satisfied with this product. Who does not wish to altimeter and heart rate, etc. and just plugging / record tracks and descendants want to know where you are or want to be right with this product! The only thing you should consider is the maps because the preloaded map is not really useful! On the subject of battery I can I say top, 3days 6-8 hrs. In operation is not a problem only in absolute terms. Reception is better than expected, even in poor weather under dense trees. Without a PC and useful software, the device is only partially available! I would like to buy again!
