Tried it once, works well so far, good enough video quality.
These goggles with a built-in camera work well and deliver excellent video and still pictures. It's easy to tell when you're recording. In that sense it's better than a Go Pro camera. It's low profile and easy to record without being intrusive.
This camera turned out to be a lot nicer than I had expected. Perhaps I have low expectations from having ordered many Chinese electronics gadgets that turned out to not deliver on their promises, but this one works exactly as I had hoped.
I got it as a present for my husband. He was not too excited UNTIL he got to use them. They are very comfortable and very easy to use.
