They said it can be a little grainy and was better in full light than diminished light and they would have been happier with 60 frames a second instead of 30 frames but said it did and OK job for the money you were paying for it. They said the mount to the helmet was good and solid and no chance of you losing it and was more than easy to operate. Also held a charge for about 2 hours of use,so for $119 bucks its not too bad a buy!
