MJR Tumblers 1 Pound 36 Silicon Carbide Rock Grit Extra Coarse

Not that good.

Liked the quantity.

I ended up using this as a stage 3, seeing I ruined 3 stage 4 tumbles,

It is pricey. Worked ok but not that much better than the 90 grit which is much less expensive

So frustrating!!! I was so excited to open the tumbler after the final polish, only to find dull rocks. I used this brand a few years ago and was disappointed. I ordered it again by mistake but figured I would give it another try. TERRIBLE! Such a waste of money!!! I am having to repeat the polish stage with a different brand and wait another week.
