Nerdwax is better than no Nerdwax
Nerdwax is almost the next-best thing since sliced bread. Almost.  It does keep my glasses up, but not exactly where I want them. Also, it is tricky to keep it from getting on the lenses if I need to wipe them off during the day or remove my glasses to rub my eye. I watched the videos on the website. Don advises rolling up the Nerdwax and applying with the edge, but once the edge is worn down, you have a rounded cone. Then what? It's harder to apply it correctly from the rounded cone than from the brand new clean edge. Nevertheless, Nerdwax is better than no Nerdwax, so I expect that I will keep using it.
