Where only limited item description

After my MTB handlebar luckily was not too thick for tightly dimensioned bracket was a first test nothing in the way. Weather permitting, the holder proves to be sufficiently stable and even a rudimentary operation of the phone is possible.

Biggest deficiency and thus a Killer: The attribute "Waterproof" or "dust-and weather-resistant" is absolutely exaggerated or simply lied.
A test (fortunately with a paper towel instead of my phone) in which the mount bracket was mounted in light rain on the bike for about an hour led to the following conclusion: The entire interior of the bag, including the paper towel (the phone would not it fared better) were completely waterlogged. The removal of the bag from the handlebars and press gently and tilt the wet bag meant that the water ran out (!).

For the all-weather cyclists it is so absolutely useless.
For me as a fair-weather cyclists it is just about acceptable. You have to see that his phone is brought quickly enough to safety in a flurry halt.
But a buy rating I would not give.
