How long have you owned it:
More than six months
Cons:
No Performance Improvement, Poor Interface
Describe Yourself:
Aspiring Film Maker
Bottom Line:
No, I would not recommend this to a friend
Only on/off and record buttons work properly. All of the other buttons (zoom, photo, focus, and play/scan) cause the camera to pause for several seconds. It is not very useful for action video.
