Conveniently, solid and weatherproof - those were the three aspects that play a role in my purchase. After so some tours over hill and dale and also by heavy and persistent rains (up less than 30 minutes of strong continuous rain) I can say that I am completely satisfied. The operability and visibility are good, the light sensor is not blocked (important so that the brightness can be adjusted upward). The holder was quick to mount on the handlebars (and also decreases again) and the bag is only clipped, the whole thing holds bombproof in the set position. While the engagement and disengagement is rather stiff (possibly borderline For women with less power), but it holds up very well. Rainproof it is on top of that after my past experiences also. Furthermore, practical: The two zippers it is also possible to have plugged headphones (by the displacement at different points, so it should fit on each phone). The bag comes with two differently thick, firm foam inserts. Both together have exactly the necessary space for a Galaxy Note with BarelyThere Case; without the thinner liner also a thicker case should fit and without any deposits has one almost like a flat storage compartment under the phone.
In short, I know of no safe way to attach my Galaxy Note on Fahhrad. Unrestricted buy recommendation.
