"I upgraded from the V737W to the V747W. Never had a problem with the prior unit, just wanted to go full HD, and there is a difference between the two. The 747 is crystal clear, and like the 737, provides a rock steady video stream of your road trip. I only wish the card weren't limited to 32g. I record and download to my PC the video of each day's off-road adventure, but the 32g isn't large enough to cover all the hours on the trail. Overall, I'm extremely happy with the camera."
