    • 5 years old and still works great
Bought this 5yrs ago as a basic tumbler and have run many courses of stone thru it. It works great! The bad reviews about leaking sound to me like they just didn't get the lid on properly. And yes, it is kind of hard to get the lid off, you have to have it on tight and sealed so it doesn't leak. The noise is so so, I mean you are tumbling rocks. This is a good product and I would order it again. ... show more

    • fantastic set for a beginer
My grandson was thrilled with this tumbler from National Geographic! He had often seen my son, his Uncle, use his more advanced tumbler and would hike with him looking for the perfect rocks. Living in the Rocky Mountains, rocks are very available. With my sons help, we decided this would be a good beginner set. It's lived up to our expectations. My daughter will be able to purchase more of the grit as needed. My grandson took the whole set to his school for a classroom show & tell. His classmates were impressed and the teacher plans on purchasing the same one from National Geographic for classroom use. Future rockhounds in the making. The noise level is normal for a tumbler, it may be a bit loud though for some folks. ... show more

My second grade students became interested in rock tumbling this year after another student brought in their collection. Soon they started collecting rocks on the playground. I knew I had to capitalize on their excitement, so I found this kid friendly rock tumbler. First things first, it is AMAZING. It comes with everything you need, including cool rocks ready to tumble, although you’ll probably need to restock the grinding powders if you’re going to do multiple sets like we have. A few things to note: It is hard to open and close. Have someone strong on hand to do it, because I struggle to do it myself. It is LOUD. I mean, it’s rocks tumbling in a jar. Of course it’s loud. But find someplace to set it up near a plug because it’s going to be distracting otherwise. In the classroom, we stuffed it in a cabinet - still made noise but muffled it enough that we could still focus. At home, we did it on the back porch. I’m sure the neighbors could hear it on quiet nights, but oh well. As long as you muffle it, it’ll sound like a white noise. Last but not least, this process takes a lot of TIME! About a month from start to finish. Be patient. The good news is that aside from opening it, filling it, and plugging it in, there’s minimal upkeep. You just leave it alone and let the tumbler do its job. Opening it every week was the highlight of our week. The process is so cool even after just the first cycle. It’s so worth the time it takes. Don’t drain it in your sinks. The gunk will mess up your pipes. After the last cycle, the rocks won’t be fully polished. We bought some mineral oil and polished them ourselves for a nice sheen. Worth the additional extra few bucks. After school let out, I brought it home to do it again with my toddlers. They loved it just as much as the big kids. I would recommend this to any future geologist in the making! ... show more

    • Gift
I bought this as a gift for a nine yr old boy. He loved it! It takes a little time to get results but once he did he was hooked on rocks! It’s a little noisy but the results are good.

    • kids need help
fast shipping, easy direction, this was great idea for child that loves rocks, but not easy to open drum after using... because of days suggested the noise level is loud, sounds like down pour of rain. we moved it into another room with door shut. only 1 set of the mineral packets comes with this unit, will have to order more to finish the stone collection that was inculcated. ... show more

    • Neat and fun to do, but SO NOISY
Our first rock tumbler. at this time, I've only done the rocks that the set came with and used all the grit provided. I have to purchase more grit before I can do rocks that we have personally collected. I am waiting though. Why? Because this thing sounds like a rainstorm in my garage. Yes, I had to keep it in my garage because of the noise level. It is so loud. That is a bummer. Also, it's showing wear and tear already and I have literally ONLY done the rocks it came with. By the time I got to grit 2, I noticed bubbles in the inner liner. When I'd clean it out after a tumble, I'd push the nasty grit mud out of the bubbles and next time, there'd be another bubble in a different location. I've only had it 2-3 months, so I hope this is not indicative of the lifespan of the tumbler. Once that liner starts cracking or breaking, it will no longer function well. Hopefully, the bubbles will not escalate into anything else. Finally, the lid gets harder and harder to remove with time. The first two grits, I could remove it by hand. For grit 3, I had to get my strong teen son to do it...By grit 4, he had to use a jar opener and barely got it open. we try to clean it well between tumbles to ensure no gunky mud build up is present, but that made no difference in our ability to open the container. Pros: Great start up kit for the price, with several good items included; Seemed to accomplish it's purpose of prettying up the rocks. Cons. THE NOISE. IT IS LOUD. Wear and tear on kit after just a couple tumbles and increasing difficulty with opening lid. I won't buy this particular model again...but I would still recommend it to others for a first time tumbler. My kiddos love what it can do and loved the final product. ... show more

    • Love!
I like this a lot. I wish it had a switch so I could turn it off without unplugging but overall very satisfied
