Waste of money
I ordered this as the brand I wanted was out of stock. Even ordered to bottles. This stuff is worthless. per instructions, let the product dry on your lenses.This takes quite awhile. You may also dry with just your fingers, scratch them? After dry then you use their tiny cloth to wipe. Your glasses will be smeared  up with no visibility. It said it may take a few applications to start working ,used it a week & still nothing. I think it makes your glasses fog worse. So your chose is either don't use the stuff & take off your glasses to let the fog lift or use this & have smeared glasses. My actual rating would be a zero
