VEVOR 185mm Magnetic Jewelry Tumbler Polisher - 2000 RPM Adjustable Speed & Timer for Metal Finishing, Jewelry Making, Watch Repair & DIY Crafts - Professional Jewelry Polishing Machine for Small Parts Cleaning

I took a leap of faith on this as it was listed on Amazon for $100 which is about half the price of the next cheapest magnetic tumbler. I received it today and watched a few you tube videos on this tumbler specifically and magnetic tumblers in general. The instructions with this machine are horrendous but I'm not going to ding them too badly for this because I was able to find so many helpful videos that it wasn't really a problem. After running the shot that was included through a few cleaning cycles, I dropped in some bronze metal clay pieces that I hadn't bothered to clean up very well. After 30 minutes they came out beautifully.If you've investigated magnetic tumblers and hesitated on this one because it seemed too good to be true, I would advise you to proceed. I will update this review if something happens to change my opinion but for now, I'm thrilled.Edited to add: The machine is a lot bigger than I expected. I added a picture of it next to a box of 37 pound cat litter as a point of comparison. It is solid - definitely not lightweight. I have also attached picture of the bronze pieces that were my initial test. I think I ran the Dremel over the heart but the other pieces were only cleaned up out of the kiln with a brass brush.
