I have purchased three of these items.  However the first two never lasted longer than six months each.  The fist one had battery issues the second one had the internal gears strip out.  I wasn't smart enough to return the first two under the warranty program.  If the one I'm currently using should fail within the warranty period I will see how that works.  I like having my pink salt and organic pepper in one quick to use tool.  We'll see how number three works out.  More to come.
