I use this holder for a few days and am completely thrilled. The holder can be easily install and holds bombproof on the disc. Have they also a few days ago several hours drive away, over bumpy roads, with cold in the morning, with defogger, subjected and have to say, just perfect !! The iPhone is sitting without wobbling in the holding tray which scratch the while driving makes virtually impossible. The reinlegen and rausholen is also child's play, this device holder should be rotated 90 degrees (landscape mode). The retaining clip is spring loaded therefore, large scope exists without breaking something, or is liable to bend. Holes on the mount system enable a perfect shop and operate the iPhone while driving. What I'm also very excited are the buttons to adjust the x and y axis. So to speak angle adjustment. Unlike other manufacturers who use any wheel and screws, you have to press here and only turn heads. The setting is done in several stages so that once set, nothing can be adjusted by mistake. It always retains its preset Positon also during operation. I am totally thrilled by the support and would unreservedly recommend again and again. For me the best support in the market with a super price-performance ratio. From me full marks !!!
