I had the smaller version tumbler which worked pretty well. This tumbler however came with a faulty motor that was not powerful enough To turn the barrel. Vevor sent me a replacement motor, but it worked for only a couple of weeks then died.
It appears to be a bad production batch which is probably why it currently says out of stock. I haven't got the time messing around preparing video evidence to try and get another faulty motor sent to me.
I guess I will just bite the bullet and go buy a proper rock tumbler from a lapidary shop. Bye Vevor.😢
