I've had one for a little while now. Not bad, BUT… two things that annoy me.

Out of the box, if you plug one into an external 5V supply while it is on, it turns off immediately thinking it's being plugged into a computer. They fixed this with a firmware update. It's worth noting the internal battery runs for 4 hours.

I'm finding when the unit gets warm, it becomes reluctant to turn on or stay on. Quite often I've gotten to my destination, and noticed the damn lamp has turned itself off. Or the camera has turned itself off and left the LEDs blinking. So a little unreliable.

Which is a shame, because the concept is brilliant.
