4 Piece 2.2" Aluminum FullMag Grinder by Zam Grinders

So far I have put almost an ounce thru it and it’s doing awesome.

Within 2 days of having this grinder, the thin barrier separating the magnets between the top pieces started to come apart so I had to just peel that off. That's whatever, changes nothing, maybe it's supposed to come off I thought!

Within 3 days however, the magnetic ring of the middle chamber separated from its piece, so the magnets are stuck together but the grinder does NOT stay together at all. I will have to reach out to ZAM or super glue it or something.

**Response was very delayed and over a month out am awaiting replacement part, though it is supposed to be in the mail!**

The teeth don't come down far enough and you are left with many pieces of smashed nugs.
It also grinds all my weed WAY too find - with my old sharpstone's I could get a nice fluffy loose grind, or flip it if I wanted it fine. This grinds everything too fine, and on top of that: the mesh screen is a HUGE micron size, so I'm having way more soft material and kief separating from my ground nugs than anyone would want.

**Upon checking these are 250 micron, or 60 US Mesh. Not 60 micron**

I thought the magnets were a cool idea but the build/design quality does not hold up. The issues are numerous; I can't recommend.
