We purchased two toto drake II toilets for the great reviews.  The glazing on the toilet bowl top is not that great.  On the front lower edge, you can actually see the grey clay body.  On the back of the lid, it is not completely glazed at all.  We ordered two toilets and both are identical.  So I guess this is not defective, but certainly not what we expected.  We will go to a plumber supply house to see if their floor model has the same glazing problem.
