I'm completely satisfied with this grinder. Like the other reviewer, I've had it for a couple months now but I've had no problems with it. The teeth seem sturdy enough to give me the impression that they won't be breaking anytime soon, unless I start grinding stones. It grinds my bud very very finely, almost to a powder. There's also a small compartment built into the die that took me a couple weeks to discover. I don't use it myself, but it was a pleasant surprise. The only con I can think of is that it often makes a squeaking sound, which I suspect is from the friction of the plastic rubbing against itself. Also, none of the fancy stuff, like multiple chambers or kief screens, but I wasn't expecting that for a $5 dollar grinder

This was my favorite grinder, I bought it back in Dec 09, and received it in the last week of Dec 09. It is now the first week of Jan 10 and i can no longer use this grinder. After using it about 10 or so times most of the plastic teeth have broken off. I would suggest buying this if you never want to use it for a grinder. Very unhappy with it, but i suppose you get what you pay for.
