Purchased primarily for the possibility of fixing my phone on the grid of Central ventilation of my car, I can not say I'm disappointed or pleased the article. It performs its function. But it is not practical in my car (Peugeot 307) ... Indeed, you can not adjust the height of the phone on the support. Once the claw in place, the support prevents access to the CD drive my car radio ... Worse, he presses some buttons on the car radio. And once installed, you have a one in two chance of breaking it wanting assembled (the plastic is hard and brittle, and obviously the ability to remove the claw was not part of the specifications of the engineers who designed the gear) ... The arm of the suction cup is too short for my taste for comfortable use of the phone by the driver.
If you need a bracket to secure your phone on your car's vent, make sure you have at least 7 or 8 centimeters free under the fastener.
Another note, the carrier leaves a large central space for connectors (charger, ...), but not on the sides, so if the headphone jack is on the bottom of your phone, it may be unusable when the phone is on the support.
In the end, disappointed with my purchase. But not necessarily the fault of the product.
