I posted this on the other thread but I guess no one has posted a review for the cardock.
I have the stock HTC One X car mount and it is not a joy to use.
The stock relies on these grooved sides to hold the phone in, and when you slide in the phone sometimes you have to wiggle to get the USB to plug in. Further, because it holds the phone pretty tightly, it's not easy to remove the phone. I have to use both hands to get my phone out of the car mount.
I guess it just comes down to the fact that it grips the phone really tight and there is not a "catch" to release. You kind of squeeze the phone into the tracks to place, and pulllll it out when you're done.
The good news is that the suction cup works really well. It's very stable and it had not fallen off at all in the last 48 hours, even when I am tugging on it to get my phone out.
The metallic joint between the suction and the arm doesn't really rotate except in a circle, you cannot change the angle it comes out at. The joint between the phone holder and the metallic arm is more mobile.
The phone uses USB to charge. The USB clicks into the bottom and works well. It comes with a long cord, I'm not sure how long but plenty to reach from my cigarette lighter to the windshield w/ comfortable excess cord.
I had been having some issues with the USB not perfectly fitting into the phone when I squeeze the phone through the tracks, but the track is so tight that I cannot maneuver the phone to get the USB to go in. Each time it's maybe 1mm off, but it's frustrating. Twice I had to remove the stand from my windshield to get it in.
Once it's setup, however, this is a very stable stand that will keep your phone very secure while driving.
