Using a wax dabber, the wax eventually begins to stick to the sides.  It happens.  This product significantly reduced that occurrence, and makes the glass far easier to clean.  Some wax does get left behind, but it forms little specks in the water, as opposed to sticky masses right at the water line.  I assume that if the vapor is not sticking as much, it's also more efficiently passing through the glass, which is greatly desired.  Having used this product for several weeks, I am completely sold on it as a solution to a common problem.  Because such a small amount is needed for it to be effective, one bottle will last me a very long time.
