Worked as advertised
I'm new to rock tumbling, I've used a few different polishing grits and this is the best one so far. I ran this polish cycle for 7 days and am happy with the results.

Very little product.
Buyer Beware! Read the small print on the size. This is a shockingly small amount of grit for the price. You might get 2 tumbles......maybe. I've paid less than this for 4 times the amount and just as good. Very misleading and sneaky.
