Bought this brand because I am cheap and you got the most ounces for the buck. Works OK, but nothing special

Waste of money and time!  In my honest and independent option, scale from 1 to 10 as 1 is being the worst and 10 is the best, this product rates between 2 and 3.  Instead, buy Spit (Jaws).  You will be totally happy.

The only anti-fog spray that I found that really works.
I have tried others, but I always go back to SPEEDO.  I won't change again.

The directions are confusing. Are you supposed to allow the anti-fog to dry and then rinse, or rinse and then allow to dry? Either way, my goggles fog up.

I've had terrible results using the Speedo anti-fog spray. You have to spray the goggles down, rinse them out, and allow them to dry. I've tried rinsing a lot or just a little, and both result in totally fogged up goggles. The TYR brand spray works MUCH better, and no waiting to dry.
