Looking for support for my iPhone 4S, I found this Sticky-Pad easy to install and very effective, even on a high rounded surface. My phone fits comfortably even when the contact occurs only on 3/4 of its surface in length. In addition, the carrier makes the phone very "deleted" it bothers me closer to the gear lever ...
One complaint I have received 1 black sticky-pad (very good) and 1 translucent (which should quickly turn yellow sun exposure) ... 2-Pads Sticky black have been better ...
