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.

Works great with one issue
It’s very difficult to get the lid off after each faze of polishing. I wish the top had a lip on it.

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!
