Title: Buy a Mask with quick release lens system
Review: Terrible design to incorporate this lens into a mask. It is the most user-unfriendly system I've ever seen. It takes an hour to replace the lens. That's with tools. I don't know how long it would take if you tried to do it the recommended way. Also, lenses are limited to a 1 year lifespan and must be replaced every time you are shot within 10 feet. Buy a mask that does not require such effort.
