Lens changes are a pain
strap isn't very secure
I bought my Proteus Chameleon from a friend, and I haven't looked back since. It fits like a glove, peripheral vision is amazing, and the upgrades are wikked...(the vortex fan is great and you can even get a custom 2-way radio system installed, earpieces fit where the round ear caps go and the mic snaps to the front of the mask...PURRRRfect for scenario games)
I replaced the lens not too long ago cause I always seemed to get gogged...I asked everyone what they saw when I was bunker-jumping, and all they said was "Your lens"...so I changed them...and man what a time I had doing that...If you ever plan on doing a lens change, take the afternoon off, cause it'll take you that long to do it.
All in all, this mask is amazing.
I give it a 10, even though the lens swap sucks...you don't do it often enough for it to really matter
