I've been playing airsoft with this mask for a good while now and here are a couple of things I've noticed, having multiple lenses is awesome and I like the yellow (low light) lens a lot more than I thought I would. I definitely use the smoke lens the most as it provides some glare resistance and it looks the best but don't expect these to work like a nice pair of smoked goggles or sunglasses. My only real complaint about the lenses is if you wear a balaclava you might get some light fogging on the lower part of the lens (anti fog spray takes care of this easily) and by far my largest gripe is that the lenses get scratched and scuffledThe mask is pretty easy to install onto a helmet but I would not recommend taking the helmet off of the rail every time you get back to the safe zone because unless you have a friend to help you it's a pain in the butt to putt back on by yourself.

Pros;
-fairly inexpensive
- 3 lenses
-stays on well
- comfortable
-looks great
-large lenses (great fov)

Cons:
-lenses get scratched easily
-hard to get on once removed off of helmet
-instructions are garbage

**PLEASE READ IF YOU ARE PURCHASING THESE FOR HELMET USE**
To remove the paintball mask style strap is comes with there is a tiny screw under the strap the you have to remover (along with the lens) to be able to get the strap off.

I ordered a couple of these knowing they run a bit small, and they work perfectly for my 8 and 10 year old daughters. We have not had the opportunity to test the helmet mount system, but it will only work with a FAST style helmet; an ACH with OpsCore rails is not going to line up correctly.
These are pretty light, and we haven't run into any fogging issues. You can breathe easily with no problems. The lens clarity is good, and they come packed with protective films on both the inside and outside of the lens, which I thought was great.
My only complaint is that these need a top strap to keep them from sliding down. I ended up just running some 550 cord to the plastic mounting pieces the elastic hooks to, and that worked perfectly. I let the ends hang out so it can be adjusted for fit by just pulling the cord in or out. I would definitely recommend these for kids (or very small statured adults).

The instructions are like reading hieroglyphics, it was kind of a pain to assemble and mount to my helmet. The mask runs big on my fast helmet and makes it hard to get a proper fit but it's possible if you make some minor tweaks.

I've had no issues with fog and it's surprisingly comfortable to wear, but it eliminates the option of ear-pro unless it's a mesh screen.

Overall kind of a hassle, looks great in action.

As you can see from my pic, I'm a pretty big guy. I'm 6'3 230lb. Full grown adult. Some people complain that this is too small for an adult head. As you can see it covors my whole face and jaw line. Is adjustable while on helmet very comfortably.

Others have mentioned the rails being loose. That's not true they are designed to be easy to tighten like a zip tie. Goes one direction easy until locked in place but doesn't move the other way afterwards.

I would have given a 4 star because of one major issue that all masks in airsoft or paintball seem to have. Fog. They do fog up very easy. I would suggest buying an exfog or some other kind of fan/antfog system for this. Especially if you plan to mount it on your helmet.

Durability is there too. I shot the lense point blank with a 450fps dmr on .32g bbs. It scratched the lense but no chips or cracks. ((Airsofters will understand this)) havent worn it to any games yet but I figure if it can handle my dmr at point blank it can probably handle any other airsoft rifle at a distance.

I bought this for my airsoft helmet to attach to which it does perfectly. I think it looks fantastic and feels quite robust. The only gripe I had was with the included screwdriver which stripped both screws when trying to remove the headband attachment. Was easy enough to fix but just something people should be aware of
