I finally got to field test this fan. These went on my full face mask. This all happened on a normal day in May. I got my new Proper BDUs so they were a little warm. This fan was so quiet, i thought it broke or stopped working. Fortunately the fan was still working perfectly and at the same time almost too quiet. Then it starts POURING rain. I thought for sure this little fan would short out or something. after about an hour of solid rain, we stop the game. The fan still worked after getting rained on directly for over an hour. Not to mention the fact that i had NO fog the entire day. Just to test it i kept it off until i had fog built up on the top of the lense. I flipped the switch and in about 3 minutes the fog was gone. If your going to make an investment into your gear, this is worth every penny.
doesn't cost much
eliminates the fear of fog, which always is a good thing
small but powerfull
...too quiet (you will think its broken because you can't even hear it when its 5 inches away from your ear)
you might need to mod your mask, but its not too difficult
it could break if it took a direct hit by a BB, but it's not likely to happen
If you own foggy goggles you know how depressing it is to stop and wipe out your mask every 5 minutes. You will thank yourself when you buy this fan. JUST BUY IT.
