Skunkteeth, Well done on the price. But the battery you show in the pic above is not typically rechargeable.
Can you tell us what you did about the fan noise? Most people say the fans are loud enough to interfere with communications. Can you adjust the speed?
And batteries need to be replaced fairly often-sometimes during a scrim. Can you change batteries without taking off your mask?
I think most people go to fans because they found antifogs to be unreliable. What do you think?
