Another "real" review...
I have been using this weekly on my marble counters since March of this year.  I have to say that it not only brightens up the honed surface, it actually looks like it is minimizing some of the etching that naturally occurs in marble.  I gave it only 4 stars because the smell is very pungent, but it is a great polish. Spray it on, spread by wiping it on in a circular motion, let dry, and then (using a little elbow grease) wipe off ("Wax on, wax off, Danielsan").  Nice feel and nice shine. I definitely recommend this for those who have natural marble countertops.
Rating: 4 stars
