I really liked these salt and pepper grinders but after  a few times of using them, for lack of better terminology, the medal bracket/spur in the cap cane off.  This connects  to the medal rod which lets you grind.  Try to push it back in but it wouldn't stay.  I was happy that the company sent me a new set.  The only problem is that they to did the same thing.  So I decided to glue it in with Monkey glue, now they work great.  I like the fact that you can change the coarseness.
