Despues de leer y seguir las instrucciones detenidamente las bandas se se siguen rompiendo despues de un par de horas de uso. Ya he ajustado el paso de los tambores poniendo cada vez menos y se siguen rompiendo. Quisiera llegar a una solucion para no tener que regresar el producto pero si no se puede tendre que regresarlo.

I have ran rocks for about 12 days 24/7. So far it works well. I have seen reviews of them smoking, but mine is fine. Just pay attention for the first few hours I guess. Pay attention on the barrel on the power switch side, my nut came unscrewed and my barrel leaked a little. I caught it early and cleaned it up. Worth it to me if it's one of the ones that works.

Very easy to use my son loves it

I purchased this in April of 2022 and beginning of may 2023 it is now dead. Rock tumbling takes time. About 1 to 2 months per batch, through all its various stages. I performed weekly maintenance on this machine by cleaning the plastic covers on the rods and re-lubricating religiously. It does come pre-lubed but would advise adding more to it and working it in before adding a load to it. It would never level the cans properly to keep centered in the machine. I attempted to tune the cans to keep them from shifting. However, they would just crawl to one side regardless. The tabs on the side do not help keep centered. Once they contact the tab it eats away at the tab via friction and also adds to the amount of noise it makes. Once the cans shift towards the heat fins they will just grind away and the knobs and make a fairly loud constant squeal while it runs. The "bearings" that hold the rods the barrels ride on are plastic and have failed. Even with routine lubrication it does not stop the weight of the barrels eating the plastic that retains the rods they ride on. This is not a long term machine. My suggestion to the manufacture is to really take a good look at where this has the points of friction and upgrade those parts to something that can displace that load in a better fashion. Metal bearings would be the first thing I would start off with. On a good note It included 5 belts and only broke one when it finally failed.

This thing is rad! I've had it running non stop since I bought it in May 2025. So 5 months now. Still going strong! It's waaaay cheaper than the other name brand tumblers, but it is worth every penny so far! Just fill your barrels plug it in and flick the switch. Off to the races! The kids are having a blast seeing the rocks after every grit too. Makes for a good time! Obviously it's noisy, put it in your garage.
