In reply to The Lemming:
Not the cheap Vivitar go-pro look-alike. It's crap. c.£45 from PC World down the drain.. There's another at c.£85, but I wouldn't bank on it being much better. Apart from the camera's many shortcomings, the various mounts seem to have been designed by someone who had never seen either a bicycle or a helmet before but reckoned he could manage a mount. He was wrong. All I wanted was a basic camera for a commute. Complete sodding waste of money.
Hope that helps, so that some good may come from my purchase
For those interested in such things, it has a wierd characteristic whereby, for example, a bus lane white line changes apparent dimensions as it moves across the lens. Similarly, objects bend and flex. It's most disturbing to watch. Still, you can make out the basic sequence of events, but the ability to read a number plate on a moving object is down to luck.
