Works, but applications don't last long
The product works as described with a fresh application. My glasses don't slip and the wax is unobtrusive.  However, the wax will dissolve and your glasses will start to slip depending on how oily your nose bridge gets. My face is rather oily and I notice that I need to reapply every 2 to 4 hours. For maximum effectiveness, clean your nose and glasses bridge before applying the Nerdwax. I still have some left after using it as needed for 3 months. I'll probably pick up another stick once I'm out.
