I just got it this weekend. I love it.
*EDIT* -Oops. Actually, I got the non-aluminum one:
THE ORIGINAL 2.5" CHROMIUM 5 PCS SHARP CRUSHER Tobacco Herb Grinder Non-Aluminum Magnetic Case (5parts) + 7 PART POLLEN PRESS + FREE POLLEN SCRAPPER
It was 21 bucks, and came with a pollen press. You should consider this one.
It's a nice, heavy, precision-machined hunk of metal. 2 neodymium magnets hold the top on, enough so that you can tip it upside-down and the top won't fall off unless you shake it. VERY sharp teeth, you could cut yourself if you wanted to.
The 2 screens are the same size. I thought they would be different, but they're not, so I just keep one of them in a drawer as a spare. For small quantities like you'd use in this grinder, one screen makes perfectly good keif. No need to refine it further.
As for those complaining that the holes are too big, you just flip it upside-down when grinding so that the weed stays in contact with the teeth instead of falling through the holes, That way you can control how finely-ground the end product is.
The holes are just fine for normal grinding. Used right-side-up, it grinds the weed just enough to be the perfect, uniform consistency for a joint or blunt. Besides, if the holes were small, then your grinder would ONLY be able to produce a fine powder. What if you just want your weed ground, and not pulverized? You can always grind it longer upside-down as long as you wish if you want it finer.
be sure to put a nickel or some small coin on top of the screen so when you shake it from side to side to make keif, the coin agitates the ground weed and helps push the trichs through. The little keif scraper is neat but unnecessary, you could use anything.
The press works well too, though handles would have been nice. Hard to get a good grip for maximum compression, but it works great. It'll pop-out little pressed-keif hash pellets that look like masonite.
There seem to be folks out there who insist that a Space Case is the only way to go, but I can't imagine it being any nicer than this one.
I think it's a great grinder, definitely worth what I got it for. I keep holding it and taking it apart and putting it back together again. Feels great in your hand, too!
