The bar is way to rubbery, it is not dense enough or pliable enough to pickup anything off the paint.  I was using it with turtle wax detailing spray as the lube, and this was supposed to replace an old clay bar from several years ago and help me prep my truck for waxing.  The truck is kept outside, and gets used and abused, so there are plenty of contaminants on the paint, this clay bar did not remove anything.  The only reason I was able to finish waxing my truck is because my old clay bar still had enough life left in it to finish my truck.  This bar was of zero value.<br /><br />Like others said, it is not a clay bar, it is more like silly putty or rubber bar.
