£4.99, size of yer thumb!!!
I have 3 of these now. First video I did I used one on my helmet and one on the bars. You can't see what you've done til you plug them into a puter, obviously. When I got home to edit, the images were wobbly due to the mounts which are really really crap. I've subsequently learned to zip tie them onto bits of the bike, using old inner tube as a dampener. This works pretty well.
You've got to play around and work out the best places to stick them to get good images. Forks or handlebars seem good, seat post facing forward or backwards good too. And you need to learn what's the best angles for them, and how close you need to be other riders. I'm still experimenting, hem hem…
They are not good at being splashed with mud. I've had 2 wipe out completely after going through puddles. But to be fair the provider replaced both without challenge once I'd returned them. Not sure I'll get away with this indefinitely.
They are also pretty fiddly. There's only an on off button really, but it's hard to operate even without gloves on, and there's a little blue light showing it's filming – it's dead hard to see if this is on or not, especially in bright sunlight.
The images are not bad – for a fiver fer ****'s sake! I've used them in varying conditions, including night rides round Wharncliffe Woods and somewhere on the lancs/yorks border, the lakes, the Alps. They seem to cope with quickly varying lighting, like in forests.
Their run time is pretty good. I've just switched them on and left them running for a night ride for eg, and they'll do about 2 hours, which then needs editing down and is a Simon Barnesesque experience, timewise. Need a decent card for them though, which bumps up the price to a massive £15.
What I like about them is they're so cheap you can just strap them all over your bike and mates bikes and see what images come out for editing. At this price if they get broken or lost or whatever, you're not going to weep.
I doubt they'll win many film competitions, just a bit of fun……
