You don't want to put anything wet into this, i.e. don't use it to chop up cilantro or something if it isn't already dried out, but that's the only real thing to note, and it's common for any machine grinder like this,

Also, the machine will get pretty warm if you run it too long.

It's still a great machine.

wonderful machine

The machine grinds everything to as fine a level as I want, just pulse it a few more times to get finer grains.
