Query: If it is worth shooting.. don't use this

The video is awful, the sound is overwhelming, and most important - something that is not mentioned in other reviews is that when this is mounted on your helmet - there is not way to know if it is on or off !!!The interface button are amazing hard to push.. impossible with gloves.Spend more $ and get something that you can count on..
