Decent Product But Not A Long Term Solution
Nerdwax is a decent product that helps to keep my glasses from sliding down. However, this product can only do so much, even if applied liberally, since my glasses will still slide down as time progresses—though much slower than when not using Nerdwax. The product is not a solution but a temporary fix that will improve things for the time being, and it's certainly not perfect. As long as the user follows the instructions and clean it off before applying Nerdwax, there shouldn't be too much trouble—only potential improvements.
