This product does exactly what it claims; however, build quality is suspect. The arm is an aluminum (or other soft gray metal) bar which may fatigue and break after repeated bending, especially sharp bending. I imagine most people will not being doing this, but just keep it in mind. The arm is fairly long too, so it should work for most cars.I use it with an iPod Touch 2G and the notch at the bottom does not allow me to insert the iPod all the way while having a cable plugged into the headphone jack. I need this as I use a small FM broadcaster in the car. It is annoying but I just tilt the iPod. This does not allow the bottom to sit on the edge of the mount but it has yet to fall. Also, suction cup has yet to fall of windshield and I drive on some bumpy roads, so that is a plus.The vent mount adapter worked well, I just did not want to use it.
