Q: I don't know if my unit is broken or not; however, there are numerous problems with this camera. Many people had the same complaints but they either never wrote a review to warn others of what was wrong in their units. What really turned me off about the camera were the many times it seemed blurry. When video started playing, I can see where someone would be walking through an area and everything looked grainy because the image wasn't clear.
A:
Bad review
