Nice, but needs one improvement...


Nice little grinder. It is well constructed and is heavier than you would expect. It looks and feels like a quality product. The ground product is medium/fine.

My only issue is that the bottom half of the grinder is completely smooth. The upper half has a ridged segment that aids in maintaining a firm grip while grinding, but the lower half does not. This has caused some difficulty in using the grinder when attempting to grind some larger products. I would advise that large pieces be broken down, otherwise the grinder can be almost impossible to turn.

Last forever


Pros: Super sharp and last forever and is very compact for travel

Cons: Nothing

Cosmic crusher

If your gonna vape you need a grinder to get the most efficiency.

Pros: Great grinder, easy to clean and grinds to perfect consitency

Cons: None. It is what it is.


My favorite grinder so far

Pros: It can grind to much better than other that I have tried so far. Used it for 1 year and still works like a charm

Cons: very small break in period when I would grind aromatherapy products I noticed the aluminum between the pieces would create friction and end up with tiny pieces of aluminum that are very easy to detect but after a while this does not happen

Solid grinder.


Pros: Solid, hefty, quality item. Blades are still sharp after a lot of tough use. I had some hesitations about what size to get, but the small size is plenty big for most, if not all, situations.

Cons: Nothing major, every now and then, it can get quite stuck, requiring cleaning. A three level would solve this since there's less buildup of small particles, but if you want to save some $, it's a reasonable sacrifice.
