Q: I need a replacement barrel, i have searched without finding one. where do get one?

For parts under warranty, please contact us directly using the customer service contact information locate on the box and/or the instruction manual.

Q: Is this dual voltage?

The unit has a solar panel plus batteries Just started to use the device about a month ago

Q: Can you make Seaglass in this Tumblr?

I put thicker glass pieces in the tumbler The glass came out with rounded corners Very happy with it

Q: The tumbler was so quiet for the first 5 days, then the knocking sound began. I’ve double checked the lid, etc. and it’s still happening. Why?

I’m guessing that it’s either the rocks or stones inside the tumbler, could be there is a small leak and there isn’t as much water inside. That was what happened to me. It could be the rollers need oiling also. The whole process is pretty simple, there aren’t a lot of things to check. Good luck! It’s a great hobby
