That's not my grinder, just a recent reddit thread I found.
Wow, is that a genuine SCS? Because it looks exactly like my cheap 8€ grinder I've been using for ~10 years (*after* those 10 years)
The OP says it's genuine...
Inhaling aluminum particulates is no bueno
. Lung clearance is limited, especially the more deeply one breathes when vaping.
That United Machining grinder looks pretty sweet
.
At this point, I'm not going away from aluminum grinders yet; checking my grinder, I don't have any notable wear at this time. But I take this story of grinder wear seriously and as a reminder that I should diligently check my grinder with some regularity to make sure that the surfaces are not wearing at all. Maybe I'll replace grinders more often too.
With all that in mind...
I've always been interested in inexpensive grinders. This one on Amazon is a 4 piece unique design; it's being sold under a number of names, highly rated and a big seller . Anyone here try this one?

I picked one of these grinders up
; had to try it for that price. So far so good. It's the Canadian version of the one above. $18 US.

The grinder is very well constructed and the exterior protrusions are very pronounced... no worries about slippage here. The bottom chamber measures 14 mm deep and the interior has a smooth rounded transition to the floor of the chamber. The bottom chamber is coarse threaded and takes one full turn to remove. The 3rd chamber (from top) has a little rubber o-ring to help the outside seal. Now I need to get some use on it and see
where the rubber meets the road. I plan to use this grinder in 3 piece configuration and not separate out the kief.
The Kozo grinder in the Amazon.com link now has over 6K reviews... at 4.8 stars
. I love all the color options available... though the price goes up. The black anodizing looks great and is cheap
.
The same Kozo grinder on Amazon.com also has a 4" wide version
.
I can always use the grinder in the kitchen if I don't want it for cannabis
