Never imagined the QBag ordered because I was looking for a practical and quick solution for the use of my Galaxy Note as a navigation device and not great only wanted to convert half the motorcycle. The viewing window of QBag is large enough for the music, it holds bombproof on the tank (even tested at CA 125 km / h; lt information to 130 km / h.) And you can read the display relatively well. Of course, in bright sunlight is directly on the window hardly what to recognize, but on the whole it works perfectly. In connection with a Bluetooth enabled helmet even a good call is possible. The display is easy to operate through the window; additional storage space in the QBag is not large, but adequate, just a little extra "glove compartment" on the bike ..... :-) You can quickly and easily remove the QBag also, if you take turns off the bike, and convenient for transportation with the supplied shoulder strap as well. How it behaves when it is raining, I can not say, but lt. Information is the QBag rain with a protective cover (not supplied) covered. Now I do not go every day with Navi or telephone motorcycling, and in this respect the QBag is a very practical solution for me and gets a strong buy recommendation .....
