A great buy
I liked it because it is the same depth but smaller in diameter. I got it to use for stage 3 & 4. For two reasons, this stage of your tumble your rocks are a lot smaller so smaller tumbler means donโt need to put in a lot of filler to get your 2/3 reds full. And it also means the grit from stages 1 & 2 is a lot heavier so for a better finish using a cleaner tumbler that has not been used with these grits. By using the smaller tumbler only for stage 3 & 4 will give a better shine
