Great place to order from, eat to use website, perfect advice over phone and brilliant communications, when it came to delivery updates. Wish all suppliers would be so 'on the ball' as I am still waiting on bits from another outlet, paid for 5 weeks ago !! Will be getting further kit, straight from Rap4uk.
Used it this weekend and my glasses still fogged. It helped some but it wasn't the cure all for those with glasses. When I pulled off my goggles the habervision was covered with sweat.
Anti Fog fan
Fits perfectly in my Dye i4 Mask, have yet to try it but it's not that much in the way as some people might believe and i am sure i will not get stuck under the fog of war as much as i have before.
Habervision Goggle Anti Fog Fan
Fitted to my switch proto FS, quite easy to fit had to remove nose bridge. Haven't had a chance to try it out yet.
