spent a few months reading and comparing dual channels, came down to the black vue 650 and Thinkware F750, Thinkware won out. read several comparison of the two head to head and there were subtle differences with neither being a obvious choice over the other. Black vue wasn't carried anywhere locally, the thinkware was carried at my local bestbuy where I already had an account plus got a really good deal for 227.00 for it on sale, so rolled all the extra's in to a package an got 12 month financing so I could spread the payments out and avoid interest also. now I have a better reason to get the SS out of winter storage a bit earlier
