## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Value.
*by K***Y on April 7, 2025*

So far so good. I was leary of the belts after reading reviews but had a backup plan. The tumbler has been running 8 days straight on the same belt now. The belts it came with were green so they possibly changed the material? The speeds are not super variable. The barrel is more flimsy than the others I own but truly this is great product for the cost!

### ⭐ BELTS are PLASTIC!
*by S***S on May 15, 2025*

UPDATE: I found good O-rings that replace the cheap plastic ones that come with it. Look on his site for Mr O-Ring 230. The 230 is the size you want. It's roughly 2.5 inches inner diameter, and 1/8th inch thickness. It fits well and it's made of nitrile, as opposed to plastic. However, it seemed like the tumbler is still struggling a lot with turning. The belt grips fine - great, really. When the drum isn't on the machine, the belt turns the bar very smoothly and has no issues. But when I put the drum on, it will turn VERY slowly, and then stop for a second, and then repeat.ORIGINAL: Not really a good buy. I had a cheaper one from another.. popular... site that has an orange logo and got hit by bad tariffs recently.. that lasted MUCH longer than this one. However, the motor on that one went out so I went looking for a new one. It's really just temporary to hold me until I get my vibratory tumbler in.The problem with this is that the "belts" for the motor are basically plastic. I've only tumbled ONE type of rock so far, and it was Chalcopyrite which is less than 1 day per stage, and it quit on the next set of rocks, which was agate. It would actually *start* turning, and get maybe one rotation, and quit. I turned the speed up thinking maybe it just needed the momentum to keep turning, but it didn't work. So I thought *MAYBE* I had put too many in there, so I took half out (even though that other cheaper one held *MORE* than what I was putting into this one). It still didn't work.Well, it came with about 10 "belts" (again, they're not belts, because they're basically plastic) so I tried replacing that. It worked. SO FAR, it's still going, but it does seem to be an uneven speed. The current rocks are agate, which is about 5 days per stage. That means I may need to replace the belt again before the first stage is even done! Instead, I'm going to measure the belt in a moment, and look up a better belt. (UPDATE: I have replaced it four times already IN THE FIRST STAGE on this set of rocks before finding a REAL belt that fit.)But I really don't want to buy *ANOTHER* rotary rock tumbler while waiting on the vibratory tumbler (which the manufacturer said will take about three months before they have more). So I'll just figure out a way to make this piece of crap work until then.

### ⭐⭐⭐⭐ Great Value
*by B***O on April 9, 2025*

Great Value! For the small money they are asking, this is a great little tumbler. It has been running for a week with an overloaded barrel (well over 3.5 lbs including stone, grit, media, and water) and is still going fine. The barrel is huge, but thin walled so is a but noisy, which is no issue for me. I plan to order another one
