Scott Vectra-Not comparable
JT Radar-Not comparable
Proto Switch EL-Same lens system, just older and bigger
Proto Axis-Very similar but it has hard ears and a visor
Vforce Grills-About the same build quality, but I like the proto better
King Cobra Pump-co2-gravity loader
The lens change isn't as fast as other masks but It's very easy.
I was going to buy another proto mask because mine was wearing out. I was considering the EL switch or a proflex but I didn't like how the flex's didn't cover my ears. I was about to buy a switch but then these went down to $50 so I picked up a blue one. Fits great! No complaints whatsoever! This is a High end mask at half the price. It's great for woodsball or speedball. I use it for both. It's got a good selection of lenses and they are easily installed. The rubber used on the mask is like on the pro i3's and it's really flexible. The soft chin is also very comfortable. I suggest you get one at the $50 price while you can. Great for rec or tournament play.
