Review: great basic tumbler. - works great! variable speed, day timer both work amazing! my only suggestion would be to enclose replacement lid seals, we wore through the rubber on the inside of the lid after only about 2 batches run through. otherwise quite happy with the purchase! just keep rollin'!
Review: Love this! - I often collect rocks wherever I go, I have for years, and I’ve wanted to get a rock tumbler for some time. When my daughter expressed interest finally getting one was an instant no-brainer. I liked the look of the Dan&Darci machine; it looked solid and stable, it was professional looking. I liked that it had multiple speeds and a multi-day timer. As soon as we got it my daughter couldn’t wait to get started. The machine was as solid and sturdy as it appeared and the instructions were very clear and easy to follow. We put in the rocks, grit, and water, sealed the barrel and turned it on. It made much less noise than expected. We’ve had this running for a while; no issues, no leaks, no problems … many jealous friends and family members...

A: I don’t think there is a warranty for it. However, if it’s defective call the company. They seem to be really good at doing the right thing

**Q: Can you confirm the voltage rating of the power cord? only 110v or up to 240v? thank you.**
A: The power supply will work with 100-240v. It has a US plug.

**Q: I get an error code everytime I try and run it doesn't anyone know why? I hardly have anything in it.**
A: Check the owners manual

**Q: Mine didn't come with an instruction booklet. Where can i find one online or request one?**
A: Contact Amazon or the Seller about getting a booklet. As for online guidance, doing a quick google search on how to use a rock tumbler will help.

### ⭐⭐⭐⭐⭐ Love this!

### ⭐⭐⭐⭐ A great gift for my 6yo son
*by J***E on June 30, 2020*

I bought this for my son who is very interested in finding and collecting cool rocks and "crystals". The tumbler drum is well made a rubberized to reduce noise, and seems to be water tight. The tumbler base is also sturdy and easy to use. The machine is still noisy, so we under up places the tumbler on a folded up blanket, then placed a large cardboard box over the tumbler and covered the box with a blanket to muffle the noise enough that you couldn't hear it from the room nextdoor. One downside to the digital control panel is that if you lose power (which we have several times in the last week, then the tumbler will stop (of course) but it will also lose how much time was remaining on the current cycle. But I doubt that many tumblers at this price range would do any better. Note that the kit comes with rough stones that you can polish and a set of grit powders. The grit does not seem to be reusable as it seems to get ground into a super fine powder. So if you want to polish additional stones you will need to buy additional grit.
