Wichtg for us was (emphasized as we are 2 different drivers with different smart phones) is the holder really universal and easily adjustable - and this is definitely it, I guess even greater as the iPhone 6 Plus should easily accommodate here. The cable routing is also made as simple as well.
Based on the experience in terms of durability with other products, I am assuming that we will have it a lot a lot of pleasure for a long time and not every 3 months to seek something new.
Another important aspect for us, the style suits the aluminum interior looks and not cheap but classy, thus nestles well into the overall picture.
Conclusion: for not even so much money you get a great working product, so strong buy recommendation
