This stuff works great
If you are the type of person who sweats a lot or has a narrow (or non-existent) bridge, this stuff is great.  Very well-priced and effective.  If I were to suggest one improvement it would be to angle the product that is pushed out of the tube (like Chapstick). It is a bit difficult to get the product on the pads of glasses.  Obviously, you can cut an angle yourself, but this wastes a bit of it.  Other than that, this is money well spent.
