Xperia Z Ultra fits with leather envelope in there

I'm very satisfied with the purchase. I use the holder indoor at my bike to the Trainers. Vibration may lack because nothing like other recessions described jump out. However weak point is not pinching the Phones I think but the holder consists of two parts. Firstly, the round terminal on the handlebar with quick release and then again 4 Hack feet on clamping mechanism. One comes now the driver ago against the bracket jumps this from the clamping mechanism and the Phone sails away. I have the terminals with Patex - construction adhesive stuck firmly to the holder. Since jumping from nothing. If I want to solve the holder, so I do it now on the handlebars and nowhere else.

The holder can be round rotate to the desired position. But makes sense only the vertical position, as this mobile phone resting on the Füssschen at the bottom.

Conclusion: For my use, the part is awesome. In outdoor area I doubt that a large Smarthphone will remain very long in it. I would back up the phone additionally with a stable rubber to the entire bracket. Find for the price, the part is fully ok
