Mother Nature polished that stone by gently washing it in water and sand or gravel until all the rough edgeswere smoothed away. Then the inner colors and unique composition of the stone were uncovered! You can dothe same thing in your Rock Tumbler; it is faster than Nature, but still takes time and patience. You can expectto have beautiful, polished stones in 2 to 4 weeks.

Update: The seller reached out and refunded my order. We purchased a new unit and all works perfectly! I recommend this product and seller.I purchased this for my daughter for Christmas. Right out of the box, the motor will not spin for more than a second. There isn't enough torque to spin anything. Unfortunately the return window was very short so I am stuck with a broken unit and disappointed child.Update: after looking closer, I feel this unit was a used return and resold as new.

The tumbler was super easy to set up, the included polish was a wonderful addition although I'll need to buy more to use again. We used a gram scale to measure the amount we put inside, we followed the weight limit the instructions included and we haven't had the band break. I know a lot of people mentioned that, so we are hopeful the weight limit kept that in mind.So far so good, no leaks, no issues functioning and the rocks are coming along nicely. A good cheap tumbler. It is a little noisy but we keep it in the garage and that solves the issue! If you're looking for something to polish your stones it's a nice small size and performs great, tumblers take a long time anyway so the fact it stays together and rolls is all we need!

The thing tumbles. It does what it is supposed to do, hence the 4 stars. My only problem is the belt to make everything spin broke within a week and so did the backup. I put a hair tie on as a replacement, however, and it's working just fine.

There are so many to choose from and this one was a great Pic. My granddaughter absolutely loves making her own gems...the duration time is only a few days verses closer to a week...sturdy and sure she will get many uses over the years. Price is great.

This is very loud and the belts kept breaking every few days. Kinda annoying

This review is of the un-branded rock tumbler from Zcvtbye Store.Box label seems to say DIY is the maker.1. Size: The ads are misleading, especially the pictures. The directions that come with it say to use 125 grams of stones, which is approximately half the stones in the little bag. If you have five walnut-sized stones, you're out of luck. I thought it was a misprint, because other tumblers say to fill 1/3 to 1/2 full or more. But they really meant 125 grams. It wouldn't tumble at all until I got the rock weight down to 123 grams. About a quarter of a cup of rocks. The pictures of a handful of polished rocks must be several runs, or a different tumbler.2. Ease of use: The barrel is well built, so no leaks, but it's really hard to open. Especially after the first time. You'll need a thin screwdriver and maybe pliers. The directions, even with pictures, don't make it clear that the rubber top fits inside the barrel like a cork, and the metal cover screws over it.3. Noise level: All tumblers are noisy. That's a given. This one is about average.4. Fun? Half an hour of figuring it out, 5 minutes adding grit and water, plug it in and check it daily (a messy process), for a month with multiple rinses and refills. Then, if youre lucky, you'll have a small pile of shiny rocks. Not thrilling.Bottom line: You can get probably three to five nice, small rocks per batch. Depending on where you buy grit, that can cost you fifteen to twenty dollars. You can probably buy the same stones, already polished, at a rock show or store for a dollar apiece. Of course, you don't get YOUR OWN rocks that way, but is it really worth it?

I like how easy the tumbler is to use, I like it so much that I have ordered a second one. The only drawback, if you can even call it that, is the way the directions are printed, it would be much easier to deal with if each language was separate. But it’s not really a big issue because I printed them on a sheet of paper.They are not the quietest thing around, but if you put them in a remote area, like back porch you don’t even know they are running.The results are fantastic!
