I just got the bright green one, and I love it.
it grinds up perfectly, its got a nice size and easy to clean kief stash in the bottom. a nice size compartment up top.
seems like i was gonna break it when i fist got it, but thats just because im used to metal grinders.
overall i give it a 4 out of 5 stars only because it doesnt lock in the smell (unlike the wood or metal grinders)
however, since the price is so low, i am going to give it a 5 out of 5. you definitely get your moneys worth.

~one love~

Ok let's be honest its probably the cheapest looking grinders i've ever used. But f*** the haters, this lil guy does his job! All I have ground up so far has been dried up stuff, but hey its nice and ground. The four stages are very nice, and hopefully when i get some nice stuff, the kief will start to pile up real nice.

It works well and is excellent for the price. No-one I know has a grinder so I take this everywhere and build up a lot of keif from other peoples weed. Nobody minds though cause it saves them hours of sitting there with a shot glass and scissors!

I ordered 2 of these grinders one clear and one Turquoise (for my friend). They took about 2 weeks to get here, and the first time I used it i felt like i was going to break it, but there actually really sturdy. It has a cool little magnet that holds it closed and it has 2 storage compartments.. Grinds nicely, really good grinder and pretty cheap. Worth the 10.23.
