OK, I think I'm going to return the Virb. I can't figure out its problem, but it does NOT like to record for more than maybe 90 minutes at a time.

It CONSISTENTLY shuts down with the battery meter still reading > 50% full. Once it gets to that point, I can flip the switch, it starts recording, and 10 seconds later I get the power indicator, a beep, and it shuts down. If I charge it up and don't touch it apart from that, it will record again until it gets down to 55% battery or so.

Also, it gets very warm, almost hot.

I can't have an evidence camera on the back of the bike that just shuts off with no warning when it has no excuse. When I get home and it's not running, that means I just rode with no coverage, which defeats the purpose of having it there in the first place.

I think I'm going to have to kick in the extra $60 or so and try out a Drift HD or something. I'm really shooting for long battery life, at least 2 hours. Isn't there a bike specific one with a REALLY long life?
