Review: Loving this so far! - Having looked at loads of these tumblers and been shocked at the prices charged, this one seems to be a bargain. Very well made and comes with everything needed to get started. Good sized strong drum and sturdy, professional feel base. Useful timer and speed controls. The drum on mine came with the additional metal end (not shown in picture) which does make it run ourt of true on the rollers as others have mentioned, but it pulls off easily and seems better for not having it on there.
Review: Rock tumbler - This product is advertised on desertcart as having a British plug! It in fact comes with an American plug! Therefore a step up machine is needed to use this machine!!! Appart from that it’s good value for it’s money!!!

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.

### ⭐⭐⭐⭐⭐ Great product
*by J***B on 27 July 2020*

I really like this product. It's no-nonsense design is easy to use and robust enough for the intended purpose. It does what it says on the tin! I've been using it for a week and am impressed so far. I'm looking forward to having some lovely polished stones in a few more weeks, that I can use in my jewellery making. The gems included in the kit are nice and the booklet hsd lots of useful info for a complete beginner.
