what is the warranty for and how long is it?

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

Can you confirm the voltage rating of the power cord? only 110v or up to 240v? thank you.

The power supply will work with 100-240v. It has a US plug.

Mine didn't come with an instruction booklet. Where can i find one online or request one?

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. You can also put your tumbler info into youtube and see someone setting it up and using it. A quick search of Amazon shows several books on rock tumbling as well as gemstone/rock identification.
