Let's say right away: the biggest problem is that as soon as there is the sun, the plastic film is full of reflections. If we add the fact that sunlight my Samsung Galaxy Note is hard to read, and of the whole becomes unusable in direct sunlight. For cons, by bad weather or in undergrowth, it's great! No worries to view the course indicated by my application (gpx track) or hear warning signals. The bag held in place (I was not convinced by unpacking). Little tip for those cables that pass over the frame tube: place a linear electric cable runs end in the bag and you will have no worries of the brakes or derailleurs. Tip: I put my Galaxy Note 1 with case (yes it happens, but the notification bar is hidden then) because without it, it can happen that the bag presses the button on the smartphone, turning off the display at once (very annoying!). In short, without the worries of the sun glare, it was 5 stars.
