much better than a previous product i'd bought which was really flimsy, the mechanism to slot in to (and importantly remove) from the air vent is very good and sturdy.
The clip in the middle on the right of the phone - well this snapped off after a few uses but thankfully just the top of it (where it actually wraps round the phone) and not the whole lug. It still holds the phone perfectly and if anything is actually easier to put the phone in and remove than it was before.
the adjustable bolsters are a good idea for holding the phone in place, and the mechanism for rotating the phone is also very good, particularly for the price. If you dont buy this one, buy one with the bolsters, in-car 360 degree rotation (without screw drivers needed) and a solid mech for inserting/removing from the air vent.
