My girlfriend wanted to start tumbling rocks and I love to indulge her interests, so I bought her this kit. I received it very fast, thanks to prime, she was very excited that I got it for her. It was very easy to use and understand which is a huge plus, but the results were not quite what she was hoping for. I am not sure if this is due to the product or her, according to her definitely the product. From other reviews it seems that some have had the same issue. Overall this is the perfect beginner kit I think they still look good, but not great and for this price, it is a solid result.

Great instructions and the grits are good variance. Was able to get some rocks off the side of the road and gravel trails that polished up very nicely and are very beautiful. Just shine them up at the end with mineral oil.

Ordered thus after i got my drum tumbler for rock polishing. The grit is legit. The plastic beads are a bit fiddley. You'll need a wire mesh strainer for the beads, they easily lodge in the holes of any colander made. These grits are an Excellent place to start for a beginner or for resupply if you got an educational kit and have used all that came with it.

I have not used the grit yet, but I've been polishing rocks for years and this grit was a good price and how different could grit be? It comes in sturdy little containers so that you can use what you need and close the lid and not worry about spillage. My first shipment never arrived so they very kindly notified me first of a delay then when it never arrived, they again very kindly asked if I wanted a refund or another shipment. I liked that fact that this is an American small company so I asked for a re-order. I'm sure I will not be disappointed.

Arrived the next day. Has all of the grades of tumbling media, extra instructions, plastic pellets not included with the original kit, and the box it arrives in fits inside of the empty rock polisher box along with all the other accessories for easy storage. Very happy with it overall.

5.0 out of 5 stars Rock tumbling needs pellets and this kit includes them!
Reviewed in Canada on August 12, 2023
Verified Purchase
The kit includes plastic pellets and as a newbie in rock tumbling, I realized really quickly that pellets are critical to keep hard rocks from smashing each other. The grit is good quality thus far and rocks look smooth. About to do a pre polish on one batch and it’s exciting. I have petwood with interspersed agate and it looks really cool. May not go for full polish, stage 3 may be enough to give it a sheen to show off layers. Great hobby for all ages.
