...you get a piece of plastic laminate covered fiber board that does not even sit flush with the top of the table saw (it sticks up about 1/32").  Supposedly this device is supposed to help stabilize the saw blade (especially a thin-kerf blade), reduce chipping and noise.  This may be true, but then it should be a standard feature that comes with the saw rather than the regular insert.  I would skip this and build one yourself for a fraction of the cost.
