MJR Tumblers 1 Pound 36 Silicon Carbide Rock Grit Extra Coarse

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

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

Not that good.

Liked the quantity.

. Breaks down too soon. no trace after 36 hrs of tumbling.

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

its grit all 60/90 grit is the same
