I"ve had the cart for awhile and have been "using" it before commenting.  Initially, I loved it until I put something (looks like a glass ring) on the granite and the remark has remained there.  I have used every granite product available on the market--to no avail.  I am so disappointed because the shape, color,"look", and usefullness of the cart, make for an outstanding product.  It just seems to have this one flaw...If you have any suggestions, I would appreciate them...
