If any of you saw my posting in another thread regarding loosing a USB recorder, I have found a lot of inexpensive (Under $10 USD) usb endoscope cameras you can plug into your smart phone and position into tight places. Perfect for retrieving little things lost in walls. I can think of a few other uses as well. Have any of you tried them?

I've seen these all over. I'm assuming the video quality is low res? At least on the cheaper ones? Also, do any of these include audio?
