I got a blue dye i4 on ebay for 70 bucks(so shop there). I got the mask and it was in good condition. Later I bought a silver mirror lens, couldnt be more happy with it keeps glare down and has a sweet mirror finish. The mask itself is verry light and is very low profile so I can look down my sights when playing woodsball.
The downside to the mask is the lack of protection on the neck and lower jaw but I have yet to be shot in the head.
Conclusion:
Over all I think this mask is worth 120 dollars new but if u go to ebay you can get a steal. I am happy with it and i beive it deserves a 10.5 out of 10
