The holder can be in my car (subcompact cars) with the supplied plugs for the air vent is not secure because the plugs are way too short (therefore a star deduction). The support comes through the inwardly curved shape of my small Amaturenbrettes with the mounting plugs not close enough to the ventilation grille. I had to stick to a flat spot of the instrument panel so that part. The mount itself is functioning properly and keeps my smartphone, an LG P500, stable position. The insertion and removal of the smartphone is very comfortable because the support arms hold together by spring force and no buttons for attaching or detaching must be pressed. Although the short attachment plugs were not to be used in my case, for the cheap price I've been buying have not looked back since.
