Editorial Review
It may be a grind to wait nearly 30 days to create polished rock jewelry with the Rolling Stones Rock Tumbler. But, as the makers write, "you are grinding in days what it takes nature thousands of years to do in a stream, river, or ocean." So, find a clean, remote area with a properly wired outlet where the constant tumbling won't disturb others (and where curious little hands won't wreak havoc), and start rolling. The first step involves assembling and lubricating the tumbler itself. Once the two-cup, plastic barrel rolls easily atop its 10-inch-long and 6-inch-high plastic base, it's time to open the small bag of gritty stones that comes with the kit. Constant maintenance and much patience will reward the owner with shiny stones in about one month. A small sampling of jewelry settings and findings is provided, along with order forms for gold-tinted accessories. --Liane Thomas

 Thumbs up on the Tumbler!!!! July 19, 1999

I bought NSI's Rock Tumbler, for my grandson, the budding geologist. While there are many different tumblers out there with a wide range of prices, I chose to buy NSI's brand because of its high quality and low noise. I'm familiar with NSI as I initially purchased the Rock Tumbler for my own son several years ago. My son used it so much, I was afraid he'd burn the motor out of it, but he never did! I only wish I'd kept it to give to my grandson, otherwise I wouldn't have had to buy a new one! The set includes everything you need to do your first batch of stones: an electrically operated tumbler, barrel, grit and polish, rough semi-precious stones, a jewelry kit, and instructions. Unlike many of todays toys which give children instant gratification, polishing rocks is a good lesson in patience as it takes several weeks to see the result. After using the tumbler himself, my grandson reported that it was his favorite present as he enjoyed the anticipation and suspense building up to opening the tumbler. He never knew what magical surprise awaited him. Even though it's been a few years since I gave my grandson the tumbler, he still collects rocks and transforms them into treasures that he often makes into gifts for others, such as necklaces and key chains. I definitely got my money's worth with this purchase. If you have a rock lover or jewelry maker at your home, you can't go wrong with NSI's Rock Tumbler as a gift!
A rewarding project! October 27, 2000

We bought this for our 8-year-old son as a project. We knew ahead of time that it would take at least 3 weeks. (It should state this on the box though.) Rocks are hard! Nature can take thousands of years to do what this does in weeks! However, it is quite noisy and can leak a little. Put it in a garage or follow the suggestion of the other reviewer about a cooler. Vaseline does stop the leaks. Your patience with this will definitely pay off! The rocks were beautiful! There were quite a few big ones, plenty of medium size and lots of small ones. My son, the budding scientist that he is, was absolutely thrilled! I was so impressed and fasinated by each rock! I could not wait to do another batch! A great long-term project that teaches not only about nature, but about how rewarding a little patience can be. I highly recommend this to all people, (adults as well) who are interested in rocks and crystals.

This is a great little tumbler to polish rocks. If you have no idea about rocks or how this machine works you need to do a little research. This is not the type of item to just buy and expect to polish rocks in a weekends time without even having to read the directions. The tumbler is also recommended for children ten years or older.
To polish rocks properly it will take a solid month of tumbling and is a three step process. This means the tumbler will be running for the entire month. The first step takes about a week, the second about two weeks, with the final step about one week. Between the steps all you have to do is clean out the barrel and the rocks and put back in with new water and the next level of grit/polish. Besides occasionally making sure the tumbler was sealed properly and is in no danger of walking itself off the table it requires no other attention. The tumbler does make some noise tumbling but not a ridicules amount. You obviously can't place it in your bedroom or living room and expect it not to be heard. Placement in a basement or garage is ideal. The power draw is minimal as it only uses .15 amps and 10 watts. Therefore, if you pay 10 cents a kWh, then the amount it will run up your electric bill for a month of constant running is 73 cents.
The instructions that come with the tumbler are also pretty good, but they do need followed. The tumbler is durable but you need to lube two points as indicated in the manual or you will put excess stress on the motor and you will burn it out. The drum seals quite well and easily if you follow the instructions on sealing which requires you to make sure the "O" ring is properly seated and you put a light coating of oil on the rim of the barrel to complete the seal.
Refills for the tumbler are extremely easy to find. Starting with the order form including with the kit where you can order parts, grit, rocks, etc. You can also purchase refill kits at Walmart, Target, and Kmart. There are also dozens of places you can also order refill stuff off the internet.
Overall, this is a great little item but it is not for everyone. If you or your children can't delay immediate gratification, or don't believe in reading/following instructions then this item is not likely for you. If you can't believe the noise it makes because you insisted on setting it up next to your bed, or can't believe that it costs less then a dollar a month to run then this is also not likely for you.
A great toy that's worth the wait! August 16, 2001

If you are buying a rock tumbler for a child or just for youself and don't want to spend over $50.00+ dollars to purchase one, this is for you. This tumbler is very durable and works like a charm. The finished productes do look like the stones on the box but with a much larger variety. It comes with everthing for your first batch of stones. The stones, grit, jewlerey, and tumbler. And not to menchin that it isn't very noisey and won't leak. But the only down side is you have to go through three cycles which consist of 3,12, and 7 days. So you do need patience but the results hold magickal suprieses. An easy, fun, and rewarding hobbey/toy!!!!
Middle School Science Class Usede This Tumbler!!! May 26, 2004

My 8th Grade Middle School Science Classes used this Rock Tumbler Machine and achieved great success and , I hope, knowledge. For the unit on rocks and minerals we did a science experiment with 1/2 of a rock sample for the Variable in a tumbler and 1/2 for a Control not in the tumbler. Students ran the entire lab for the month. The final results were great both as a science lab and an enjoyable activity. The use of the diatomaceous earth becomes another lesson. I recommend that you keep some of the same types of rock out of the tumbler just to compare after the tumbling is done even if you are not doing it as a lab in a classroom.
There is a lot of noise connected with this piece of equipment. I could leave it in a storage room. Also I recommend that you tape it onto a board or on the table as the vibrations may cause it to move. Make sure that the seal is tight so no water leaks out. This is noticed at the very beginning if it should occur and can be easily fixed.
Some students went ahead and ordered their own Rock Tumbler. I warned the parents about the noise!!!
