I've used it. It's not as aggressive as you would think, unless I'm a victim of the reported inconsistency of the Optimum polishes prior to them getting their own blending equipment. You'll want to use a cutting or orange pad with it (to make sure it breaks down...not that there seems to be any grit to break down). I'm not sure that the major element of the Optimum polishes isn't the lubrication value and letting the pad do the work more so than the abrasive in the polish.
