This may be the best grinder I’ve tried. The ability to remove the cup is awesome. No smells from any grinding remain in the SS cup. I’ve ground pepper and it can be ground to any desired fineness. The only downside is you have to use a fair amount of peppercorns resulting in more than needed. I do like the grind and have no issue with an extra jar for leftovers. The hand grinder is great at the table but this sure saves time. I have also ground mustard seed which I used to do with mortar/pestle. This does a fantastic neat job. I don’t do coffee, my coffee maker does this for me. I highly recommend this little unit.
