MJR Tumblers 1 Pound 36 Silicon Carbide Rock Grit Extra Coarse

Love this 1200 grit !! And the company is awesome to deal with!!

Received as advertised, and timely.

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.

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

Liked the quantity.

it does the job pretty good, I use it in a tumbler to sand large pieces instead to have to sand by hand.

This product was phenomenal. It helped me take a whole week off of the time needed for my tumbles! Highly recommended if time is a concern!

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