Last year I bought one on eBay for $28.00, not great and the motion sensor system is usless but we did use it at the beach and got some good pictures and the sound was so so. I like the concept well enough to buy a better one and with a 32 or 64 gig card you'll get a lot of recording. Ours has a on/off switch and if you turn the key off, it will come back on when you start the engine again. It will be nice to be able to photograph signs as we drive down the road and not get a big blur. Missed a lot of Welcome to ..., signs we wish we had.
