This was a replacement for my prior Cuisinart rechargeable salt and pepper shakers which broke and were replaced under warranty.  I like this new model much better than the old one for several reasons: 1) The new design can be adjusted to give a much finer grind - the prior design ground too coarse; 2) The prior design had separate units for salt and pepper - the new unit has salt and pepper in one unit which is more convenient; 3) the attachment of the plastic spice housing to the main body (which broke on my prior grinder) is now more robust and should not break as easily.  Overall,  I like this new grinder very much.
