Hi I have been coming onto the site for some time reading posts and today decided to join, I have a cc1 dual dashcam its a dk870 this is my third unit the 1st had dead pixels then the replacement kept losing the settings and reverting back to chinese, this one seems ok so far although sometimes it doesn't pick up the rear cam I have to switch it off and on, I am a driving instructor and I wonder why I didn't buy one years ago. I will probably upgrade in a few months to a top of the range.
