It is perfectly designed for iPhone 4, 4S, 3GS, 3G and iPod Touch. It is also provided with a nice protective shell iphone and ipod touch. It can even accommodate your iPhone without removing the bumper, which is handy.
Loading is made using a cigarette lighter power supply aesthetic and unobtrusive enough that plugs into the base of support. It will easily fit with the small Velcro provided.
The suction cup fixed and removed quickly and safely seems to drop for the phone, which was not the case at the entry level medium that I had before.
The orientation of the phone is using a ball that one desert and then tightens, and a very effective articulated arm.
The sound was deported to the support base which avoids tearing the mini-jack of the iPhone (which would damage). A mini-jack cable with automatic winder is included to send the sound to the car radio, for example.
Icing on the cake: a small sticker Dexim that is discovered at the bottom of the box ...
CONCLUSION: an almost flawless for iPhone car holder, which is perhaps a little expensive compared to low-end models. But it was well worth the money, believe me ...
