The thing does what it promises. There is sound, but it's pretty quiet. Videos also play sound in VLC Media Player but not in Windows Media Player. The lenses are super wide-angle, almost like a fish eye. It is not very convenient to walk with him, as shaking repels him. Putting it on something smoother like a bike might work better. It works great even in low light. I especially like the magnet. It's very strong and I can hold onto almost anything. This is a great party cam because nobody notices it. I just love it. PS Don't be fooled by someone who looks like this at will. My friend ordered one and was very disappointed. It's not just a brand, it's tiny and terrible. Make sure you're getting this from Polaroid and no one else, even if it looks the same, it's not.
