FYI, I destined to an iPhone 4 on a ventilation grate Grand Picasso. green buffer is very adhesive. can be too, if we put a protection around the phone. One wonders what will go first. Then the bond between the support and the buffer has already broken during installation. When we see the strength it takes to remove the phone, it is doubtful resistance over time. Finally, the green buffer is a dust magnet ... it will provide regular cleaning with a "trick" that leaves no more plush! and do not glue. Disappointed overall. It's more like a real good idea after a cleverly designed accessory.
