Another caveat for VIRB owners. The screw mount wiggles loose very easily. I've cranked it down as tight as I could by hand and twice now the screw has come out, the last time I lost the screw at speed around a corner at a stoplight and the cam was dangling from the tether at the next light (I always tether my electronics, I've lost too many things). Maybe it's because 100% of my route is chipseal and it's vibration city.

I put in a new M4 screw philips head, put in a lock washer this time, and cranked the crud out of it. I also wrapped and tightened the safety tether so if the screw loosens it won't be swinging around the spokes this time.

Oh, and I also hit the bug that Google tells me many others have had - last ride, I turned the cam on and it shut off again within a few seconds. The battery was at 40% but it went into low power shutdown. I couldn't even get into the menu enough to reset it. I finally pulled the battery out for a few seconds, after re-inserting it, the cam worked fine again.

Yes, I'm on the latest firmware.

I still like this cam. It's built like a tank and I like the design. I just wish some of these little irritations were gone; I have generic Chinese cams that don't have these issues or anything like them.
