    420 Science 4 Piece Grinder

    Nice addition. This is my go-to grinder for filling cones as it definitely grinds the material very fine. Be careful not to overfill as I did my very first use and I'm still trying to clean the lip that the lid rests on. Would have given 5 stars but I enjoy my Diamond Grind just as much in the same price range.

    Great grinder

    I really like the way it’s made but wish it had metal blades
