I picked up a pair of Pivothead sunglasses, and I must say quality for both the video and audio is much better than I was anticipating. There are many times when I am working, that I would like to record what is happening and it may not always be convenient to use a tripod setup or even a go pro. There are other times I want to record without appearing that I am recording. Very handy, it is a very good product. Takes stills as well. Ill be posting some videos on Youtube once I have done more tests.
