initially made a good impression. , Positives: It is stable and easy to mount to the bicycle handlebar. Because of the 2 zippers can be connected using a USB cable, an external battery. Inserted foam pad the score is stuck in his pocket. , Negatives: The foil reflects very strongly the sky and thus you can the Navi (I use LocusPro) hardly read. Also, the application of hair spray (a rough surface to obtain) brings little improvement. In humid weather (hot and humid, but no rain) "sweats", the film also on the inside and the display of the note glued partly on the inside of the film - wipe helps only partially and for a short time. , Conclusion: In the absence of a viable alternative, I would probably buy this mount again.
