I have only tried this stuff the one time, on a rainy foggy freezing Canberra morning. It made things worse. Had to ride with the visor up 10 minutes into the ride just to be able to see. Maybe it was extreme conditions? Maybe I didn't put enough of it on? Not sure. I'll try it a couple more times before I make my mind up.

Not all I had hoped for but it is minus 5C where I live in winter, I wouldn't say it prevents much fogging at all but when you crack open your lens it does clear faster, but as for anti fogging properties I'm not seeing it.

Only basing my review on my internal sun visor and at a standstill.
My visor still does fog up, but it fogs up differently and clears away SO MUCH quicker once you get moving.

I spent a bit of time on the net looking for anti-fog products and this was one of the top picks from that search. It works! It is easy to apply and does the job.
Also good turn around with the orders, got it the next day after I ordered it.

I tried this product because I just Couldn't Stand my visor fogging up on me all the time.
After using this, I can say it does work and I usually get 3 days use out of one apply.
The only down side is that it is a pain to apply.

works well, i apply it every few days to keep most of the fog away, although it does last a while, i thought the tub would have been much bigger by the looks of the picture, anyway, a good product! :)

This product seems to work well

Visor was fogging up so thought I'd give this a go after reading the reviews. Works great except as everyone else has mentioned you do need to re-apply it fairly often, but it's only a couple minute job and the tub is small enough to easily carry round.

I got the Cat Crap to use on my glasses on a push bike and it is working really good.A friend recommended it.

It works but it's not a set-and-forget solution. You need to re-apply it every few days / week or so. Still, it's not difficult, about a 2-minute easy job .

Life is so much easier, because all I have to is sit at my computer and order want and in a few days it is delivered and the cat crap really works. Keep up the good work Ken.

Very good product , it saves a lot of time and money using cat crap Visor Anti-fog , comes in real handy when needed the most , when the helmet visor gets dirty.

Don't let the size of this small tub deceive you, a smear is all that's needed & if applied to a clean visor before every ride, it will not fog! For around $10 it's worth it to try!
Posted by Jason on 13th Sep 2013
Definitely hasn't stopped my fogging. Wasn't aware I would have to apply it every day or so for optimal coating. It is better than it was though and for $10 still happy I bought it.

Not bad , but no miracle cure! might need a lot of it from such a tiny little tub . In the end there a lot worse products on the market , so give this a go !

This has been the only stuff that has worked on my visor and no fogging.
Don't know what it's made from but hell it's good. Maybe it is from Cat Poo.
Comes in a nice little easy store container which can be put carried in your jacket pocket.
