Universal Car Mount Holder for PDA Cell Phones/MP3/MP4/GPS - Black + Red (4.8~10.5cm)

Pros: Good mount holder at a fair price.
Clings very well to car's window.
Build quality is good.
It can swivel 360 degrees, or lean forward and backward on a ball bearing.
What I like is that the bearings can be fastened so you get a steady hold of your device.

Cons: Not one that I can think of.

Other: I got this after my friend recommended about it. Have it with me for about 1 year. Using it to Hold HTC desire smartphone to be used as GPS or as an MP3 player which I connect to my car stereo. I even use it when I watch videos while I need to wait in the car.
I'm satisfied with it.
Going to order one for my dad now.

Pros: Very very good suction and easy to use 'lock' mechanism for the window cup. Virtually any angle is possible, easy to rotate your phone from portrait to landscape position without fiddling with lots of switches.

Cons: It hasn't happened yet, but with many other holders of this type the mechanism to broaden or squeeze the walls onto the phone tend to break easily, and I don't think this one is much different. Be careful not to overtighten it or force your phone into it when its already 'closed' and you should be fine.

Other: Best quality, most flexible and strongest suction cup of any phone holder I've tried.

Pros: Good quality of suction. Strong suppport. The red accents highlighting the design. Easy to mount. Vent clip extra. By the type of fixation, it seems that you can take it out of place and put it back without losing suction power.

Cons: Fitting parts between the support could be stronger.

Other: An excellent support, better than many others, especially the type of suction. Could be a little cheaper, but still worth it.
