Already the installation is really fun - a few turns at a cog, of a much larger and therefore adaptable to any conceivable handlebar sizes tether can be best placed - a few turns at the little screw - done. The cell phone pocket is easy to remove with a click-lock and locked quickly and reliably when you replace one. Unlike previously tested Handytaschen other providers this fixture creates the compromise between stable enough (not to shake when driving on uneven surfaces too) and flexible enough (so nothing can break off with harder beats). After more than 2 months and over 1000km on some very bumpy ground, I have not the slightest doubt that this bag will keep for a long time. When push and turn pulling the smartphone little resistance and little space for gripping the device is available - that's the trade-off for safe maintenance of the device and the tatellosen operability through the front of the envelope through. So is not super fast, but you can get used to it. The shell can be zuknipsen at the opening, which ensures sufficient water resistance. Sufficient means not suitable for diving / swimming or during heavy rain, but surely in drizzle and small showers. Given the pedaling with smartphone then you had better look for strong rain a shelter - the cell phone pocket should to give after the onset of rain sufficient time before the phone what happened. To adapt to different heights and thicknesses phone models are at Pad Mat and the transparent cover is rolled from above. After rolling a velcro prevents rewinding reliable.
Test with HTC One X: fits perfectly and works perfectly.
Test with Samsung Galaxy S5: The phone is slightly higher than the transparent envelope. It can be summed up easily in the pocket and the dispay is fully visible, but the brightness sensor is covered by the black frame, which is why the mobile max darkens with automatic brightness. But can be adapted very easily, because the S5 with 1x wipe + Tap "auto" to manual brightness (which should be pre-set in daylight at a maximum) switch and also as easily can switch back again. No real problem.
