I bought a Cobra Drive camera about 3 years ago for my company car. I'd been thinking about one for a bit and this one was at Costco. I bought it on a whim... Something I usually don't do with this type of purchase.
I liked the size and the mounting was OK. I never really liked using it though. It wasn't "user friendly" to me. It has a very small screen and I had to get right up to it to see what was happening. I had it working for a while, but I had some issues that I really didn't take the time to figure out.
I have thought about it a few times since then, in fact I just pulled it out a few minutes ago. I really want something else that's easier for me to use. Something that I could use with my I-phone would be nice, but that might also mean updating the ancient version of the I-phone I use.
Since I have three vehicles, this is where I have to make a decision.... I can stay with the lower end units and have three, which would put one in each car or have one or two really nice ones that I swap around... Or some combination of both.
I looked at the Go-Pros last night. They can be set up to loop record and to run while charging, but they still lack a G sensor that will store the loop before a crash. I think you could do it manually, but if you think about it, you might not be able to reach up and hit the button after a crash.
