Nice product, great case, good fit and finish, but would not work with 5.25 x 1.5 inch glasses. Comfortable. Very reasonably priced. Needed to replace old ski goggles. I could make it work if I jammed the gasses into the goggles and tried to fit my glasses over my face, but this would be an awkward and risky move on a ski lift. Goggle fans work so well to prevent fogging that I am surprised that literally nobody any longer produces dedicated ski goggles with a fan. Unfortunately sent back, would have kept if just slightly larger.

Early on in airsoft, I found that all of the anti-fog products for goggles just don't hold up once you start sweating. Not being able to see during a game is pretty awful, particularly since you can't take your goggles off until you reach the safe zone!

Up until now, a pair of goggles with integral fans on them would cost you $100 or more. That's too rich for my blood, so I've added small fans to many pairs of Pyramex goggles to keep them fog-free. This pair is very similar to what I have made, and for the price I may never make another pair again! It works well with my bump-helmet, and the fan keeps the goggles fog-free. It does the same job that other goggles do. My only gripe is that the battery cover does not stay as well as I'd like. It's made out of silicone, and can open while you're putting them on, spilling your batteries. (So far this has not happened in a game.) A piece of electrical tape is good insurance against this.

All in all-you get a critical piece of kit for a very affordable price.

So first off, for the price these are great. It appears that the foam edge surround that sits on your face has been upgraded compared to what I saw in older youtube videos reviewing these. So have yet to test and see how well that hold up in high Texas heat.

Now on to the Dead On Arrival (DOA) issues that I think a lot of people are having. I strongly suspect it is because the plastic in the battery box inside that is holding one of the positive connection points it too thick and is not letting the battery contact with it. After I dremeled it down slightly it was enough to allow the battery to connect and BOOM it works...

So no I need to field these things to be able to give a final review on how good they work and feel during game time.

Update: I fielded these during a rainy game day and will say they performed well. I got a little bit of fogging in the top corners but I also use "Wide-I" magnetic fog wipers, used by scuba divers and I had a great time.

I used these goggles for airsoft, the original thing that led me to buy these was the built in fan. I played two, 35 minute games and the fan only lasted for around 30 minutes in the first game but I will say that it still didn't fog up at all for me, even after the fan ran out of batteries. I would buy these even if they didn't have the fan. They fit comfortable even with a helpmate and face mask. I even went in my backyard and shot the extra included lenses from 5 feet away. My gun was shooting 345 FPS and I was using .25g BBs. The only visblw damage was a couple minor scratches. These goggles will protect your eyes in my testing. I recommend for new players or even experienced players looking for awesome cheap goggles.

I have had these goggles for four months now, and fought with them in many games (using only the tinted lens). They feel like an obvious product of cheap Chinese manufacturing, but as advertised and have not failed on me yet. One star off for bad foam shrouding and reverse fan direction as stated below.

Pros
-Comes with a case and two lenses (I love the tint)
-The fan is near silent, to the point you do not know it is on
-The battery case and wires to it are fairly robust
-The lens has not chipped yet, and only gets scuffed by BBs

Cons
-Feels very Chinese; borderline flimsy
-Foam covering vents surrounding the goggles comes loose very easily (useless anyway)
-Fan blows inwards instead of outwards (reverse the wires yourself)
-Battery container can dig into your noggin if you do not wear some sort of head cover (balaclava/baseball cap)
-Connection from strap to goggle is ugly but functional

I consider reversing the polarity (switching the leads from the battery to the fan) a valuable modification to pull humidity away from the lens instead of pushing external air towards it.
