You should already be clear about what it wants for a product you purchase. If there is to be a bike-holder that carries the phone securely in first place, then it is also clear that the mobile stitzt possible fit in the holder, right? I do not know what people expect from such a product so everything, especially for that price ... These should be also be noted that the Xperia Z is water- and dustproof. The only sensible argument a protective case is therefore the protection from falling, but who buys a bicycle holder, when he must assume that the mobile phone falls out ?! Please, first time thoroughly think about what to buy, or rather why you buying, thank you.
Now to the actual review:
At first I was a bit skeptical, I want my 600 investment not enter into unwelcome hands, but I gave her time given a chance, especially since the thing is really not expensive. I had the support now being used under extreme conditions, great mountain bike tour through the forest, with great uphill and downhill. It was really very ruppelig, the wheel including me were violently shaken (which is also often no wonder). The holder has held as a unique visitor, not even slip in some way it is. It gives a right the first touchdown also feel good because you can connect them very firmly by the quick release. The Xperia Z will not budge.
What else? The support is in steps of 45 ° vedrehbar with snap, can not for the need it badly determined. The Einraster is also as it should be.
Through the quick release you get the part and quickly mounted on another bicycle, what comes in good stead.
All in all, the mount does what it should do, namely 100%. And the price is really more than fair!
