Like George I'm not a big fan of SMS acronyms, but this is worthy of a LOL... ;D
As UB suggests, and the Amazon customer review below indicates, this item appears to be intended for a market other than spice-heads:
"This thing is great you can grind about 1-2grams in one sitting.The whole thing will hold about an eigth.Grind is really the wrong word though, mince is a better description.The teeth actually mince and cut the herb rather than tear n grind like others.The build quality is professional kitchen standard, cant see how it would ever break.If Gordon Ramsey smoked weed, he would grind it in this."
I suppose you
could use it for spices, but I reckon your wrist would fail before you managed to achieve anything with a finer consistency than kitty litter.
You're much better off with one of these babies:
