It's Worthless
I liked the idea but it didn't work as described.  It's messy, stays soft, gets on the lenses, and the glasses slowly slide down your nose.  Especially if you're outside, in the sun.  A set of eight soft adhesive pads, (for $1.39) work a lot better.  A complete waste of my $10.00 and the last time I trust anything from "The Shark Tank".
