I realise that you only get what you pay for but about two years ago I bought a mini video camera off ebay for around the 40 pounds mark and it is brilliant. It got very good on line reviews. I have been thinking about a dash cam and the prices can be astronomic. However based on my previous experience why shouldn't this one be sufficient to be useful if required as back up evidence of a crash or incident?

I've had mixed results with cheap ones. Quite a few have given sporadic reliability and that's not something you want from a product that is effectively 'set and forget'. It needs to be 100% working when you really need to be. Cant imagine anything worse than reviewing footage you know would prove your innocence, or earn you a mint on YouTube income, only to find its not there or corrupted.

HOW MUCH !!!
go to "tech moan" on you tube for the best reviews, that one does sound a bit too cheap and the seller,s feedback is a bit on the low side

A118C is well reviewed and one I have works well (although was in 2nd car so didnt get lots of use.)

My daily has a blacksys cf-100 which is dual lens, and superb quality, but has a frustrating lack of settings.
