yeah I have two of these DV80's (front and back) they are fantastic devices for £12.

to try answer some questions.

they charge via usb
batt life 120min aprox
11min = 1Gb footage
so no need for a card larger than 8Gb (8Gb=88min | 16Gb=176min) at the mo 8Gb cards are £10 and 16Gb cards are £30
They record sound and video you cant turn off sound recording.
you can read number plates from a good distance.
the footage is date and time stamped.
720x480 res 30fps
all the accessories in the box are shit apart from the gel sleeves which you can loop some velcro round the slits (for a belt?) and attach it to your head tube and on your seat tube if you have two.

you can set the date and time by doing the following:

in notepad, write
[date]
24/5/20010
14:05:00
Naturally submit the correct date and time.
save and name it as TAG.txt
Then copy it in the root of cam.

(you need to adjust manually for day light saving)

glad you illustrated the successful use of a 20quid version of those. although not the best to fit on a helmet, i seem to be temped myself. how well do they seem to deal with the odd rain shower? (they seem rather unsealed plasticy sort of china thingy, that brakes in the wet)

you can seal them yourself using that stuff in your puncture repair kit ;) I use the rubber cement to seal all my lights too, works a treat
