I had long been around in supply Dashcams before choosing the F-310 and I use it now for two months during my travels. I find it almost perfect. It is more discreet and less expensive than most. Good quality of image and sound. I just background noise, but not serious for the use that I do, and it tends to overexpose when the sun is strong, but again, it's to protect me, not for turning a movie. The night I find very satisfactory quality. A lil movie? [...] The cable was long enough to go into the making of the trunk so that I had no tinkering to do to keep my grip free front for GPS. The attachment is good, just left of the mirror in my case. I recommend the shareware Registrator Viewer rather than the one that came with more limited and unstable on my PC.
