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!

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.
