That's ridiculously cheap when you consider that a spare Garmin satnav bracket would probably cost that alone.

Lots of car mad people (like me) like such things for making vids of their outings.

Yeah, and also useful if ever you have a bump or are the target of someone else's road rage etc.
I always have my cam with me anyway...needed for work, but I do bear in mind its usefulness in other 'situations'.

Also used by others to record a certain person's noisy car (coming from the right).
