I bought these goggles last October to use on the range when I help an infantry battalion as a handgun repairman. I use them when trying to restore weapons to make training videos for my new soldiers. I first used them last November when I had to qualify with my M249 SAW and I expected the sound of the gun to drown out the sound. That didn't happen and the video quality is amazing considering the price. The only thing I don't like is that when I wear my ACH (helmet) and these glasses there is no clearance so I have to remember to put my glasses on before the glasses.
