WORKS SUPER WELL!!!
Purchased the spray bottle and paste and thought they both worked super well.  Spray bottle cleaned my glasses, was convenient and didn't streak.  Paste was easy to use, applied a small amount and saw similar results keeping my lens clean, spot free and no fogging for several days.  I workout a ton in my glasses so not having any fog was AMAZING!  The trick I learned from Z Clear's website was to use a microfiber towel or cloth when using their products.
