This product does not work AT ALL.  It worked for the first 20-30 minutes of practice, then seems to wear off.  I avoided the speedo brand one due to bad reviews, but I just bought a tyr antifog and it worked like a charm.  I highly suggest anyone to go for that instead.

I followed the instructions but it work for 1/2 hour.  I usually prepared my goggles the night before, but one time I got sidetrack and let the formula dry overnight, instead of starting over I just wiped the residue with a clean soft cloth until it appeared clear.  It worked 1 hour in the pool and not a fog.  I am planning to see If one application will work for 2 days swim.

I swim six days a week for at least an hour and a half a day, and this product is great! It keeps your goggles crystal clear, and they usually don't fog up for a good while (been fine through day swim meets too). However, if you rub it too often or dip it in water once applied, some may come off and result in a bit of fogging, but it's really not too bad. My only "problem" is that once I start using it on a pair of goggles, I always have to use it every single time or they'll fog up in no time even if they're brand new. So I wouldn't use them until you absolutely need to. But besides that, they are fantastic!

I applied as directed and within one lap had severe chemical burns of both eyes (cornea and conjunctivas). Lost three days of swimming and cost an Urgent Care visit. BAD PRODUCT

I used these on some of my swedes which are notorious for fogging.  It worked great on a warm-up into a 500 (a little over 1,000 yds.) However, once I took them off and out of habbit, I dipped them in the water they started fogging up again.  The next time out, I avoided getting any water in the goggles after a set and they did not fog.  So I guess as long as there is a fine coating of this in goggles it will work perfectly, but if that happens to get washed out, all bets are off.  It is definitely better than nothing though, and I will buy more.  It is the only anti-fog I have used that didn't even slightly burn my eyes.

Finally. I have tried many things and those that worked seemed to bother my eyes. I tried this on my oldest goggles and it exceeded my expectations. I do have to use it every swim though. So far I am very pleased.
