National Geographic Hobby Rock Tumbler Kit

This is a great product. It takes a very long time to do these rocks though. I hadnt expected that. There are many steps to each batch of rocks. The tumbler runs for multiple weeks all with different grit as you go. It has very good directions and so far it has done a good job on rocks.

I bought this for my 10 year old and he loves it. He loves seeing what the rock looks like after it is polished. I would recommend this to a friend.

Perfectly awesome. My daughter loves it. She 21 today.

Good price and it works great. Comes with everything to get started. Even easy to use for kids

Absolutely love this kit! It polishes my rocks/stones beautifully! Buyers should know that you won't get "instant satisfaction". It takes time. But definitely worth it!

I had bought other Nat Geo items before for under $20 and have always been surprised but When I bought this it may be the best of all! The quality and constuction is unbeakable at this price. I have been tumbling my first set of rocks for 2 weeks and the kids are so excited they keep asking when will they be done. Great instructions and easy to operate.

This Is a high-quality rock Tumbler. I have had quite a few of these over the years from different brands and they never seem to give a good polish. I have had a lot of fun with my little ones and we have used this several times already. I would highly recommend this item it is definitely a more commercial grade rock Tumbler not a so much a toy

My 7 year old grandson loved it.

This was a gift for my great grandson and he loved it. It was a birthday present and arrived quickly.

I was really excited about how my rocks were turning out, but unfortunately this model has a serious manufacturer defect. It stops working, all lights flash, and will only run for a few minutes at a time. I tried changing the belt - it doesn't work. Hoping to get a refund or have it replaced by manufacturer.
