Cycling enthusiast, acquired in 01/2008, I am very happy at the data, except for the height difference, which is completely fanciful (on average twice uneven from one device to atmo pressure) But it is fragile, very fragile see: the first was changed free 07/2008 (case deviates) and back again as the new one has the same symptoms (impossible to change screens, keys remain locked ...) .and all that just by using about 1 time per week on average, without having it fall or anything ... I wanted to spend the Edge 705, but given the fragility of the F305, and the price of maps, I ask myself to return to POLAR.
