Product works amazingly well.  Works as advertised and stops your glasses from slipping without using some u comfortable ear wedge.  Only mistake I made was using it right out of the package during winter when it was below freezing.  The tube spinner broke that brings up the wax because of how solid it was.  I heated it up and put in a new lipstick diy container has worked flawlessly since.
