I have a chance to buy a brand new one for $50. I'm wondering if anyone has used one and if they are happy with it. It has pretty decent reviews but I'm not a fan of things made in china, and it seems most of the dash cams are. Anyway, for the price I was considering it, but I was wondering too about the rear camera, if it would interfere with my rear window shade? I typically leave mine up all the time unless Im driving with the windows down. I drive a W211 04 E55 that I just recently scored and I want to help protect her. Any input would be greatly appreciated!
