Great product

just what we needed for the Christmas holiday

Child loved it

Purchased for my daughter (14)and niece(6). They absolutely loved them. Great value, easy-to-use and ready to go for tumbling. Fun for kids and adults. We have a harbor fright double barrel tumbler and we have both barrels going at the moment. I've herd the grit isn't the best, but we gonna give it a try. I will do an update on the grit in a month-ish when we make it through all 4 stages.

Nice assortment of stones. Easy to use directions and supplies.

Lots of rocks Good sizes some small but most are acceptable

This box includes 5 different 1lb bags of rock to tumble. There is a nice variety in the different kinds, and it also includes all of the grit required for each bag.

I used it as an educational toy for my children.

Great selection of rocks and lots of materials to keep me going for months.

Offert à notre fille qui adore les pierres, la machine fonctionne bien, elle fait quand même du bruit (prévoir un emplacement isoler) surtout la nuit. Les explications sont plutôt claires et elle est assez simple d’utilisation

Hay tres bolsas y los 4 sobres para pulir, con una bolsita para llevar algunas piedras y una lupa de regalo. Justo lo que buscaba

My kids love using the rock tumbler and it’s become a weekly habit we enjoy as a family. The quality and the assortment of rocks are exciting every time.
