Got this to put in my motorcycle helmet to prevent any fog from happening and after riding all year round have never once had an issue with fog blocking my view while riding.

It does what it says it’ll do. Helps stops fogging and keeps your visor clear. But installing this thing was like performing open heart surgery. It almost didn’t fit quite right, and the entire time I was worried I would ruin it by smudging or bending it wrong.

The pinlock inserts are great at reducing glare and preventing fogging. My wife and I had them in every helmet we have owned over the past 8 or so years. Recommended!

Keeps the fog out completely. Sprays don't work but this does. Worth the money

The only time i noticed my face shield fog is when i left the helmet out with the bike on cold night while playing tennis league match. The moment i put the helmet on it does fog and that's why i had the face shield in up position first and let the air clears the fog while the bike moves slowly. A few minutes later the fog is gone and i close the face shield. As long as there's air circulation going though the inlet then there's no fog that i can remember.I didn't notice the face shield fogging up during spring and summer.

Use mainly in sub 50 weather works great until sub 40 starts to fog to an extent around the edges with or without vents open, but at least I can still see the road. Probably won't apply to most riders

HJC was a lil odd to get the numbers straight to figure out the compatible fog lens but this is what it says it is and does what it is supposed to do. Been out a few times and no fog. Just like a double pane window, it keep a pocket of air between the fog lens and visor. Make sure to put the side with the rubber border on the visor. :)

Easy to install. Works perfectly. I’ve used it down to about 30 degrees so far, no fog at all
