Great Glasses Cleaner!
The Koala cloths are great for wiping away dirt and oils from your glasses.  The cloths are nice and thick, and don't slide between your fingers and the lenses like thinner cleaning cloths do.  The solution is okay too.  I'm not sure how to determine the fluid's effectiveness.  A quick spray adds some wetness to the lenses to help you wipe away dirt and gunk.  Overall I'm very satisfied.
