How much rock fits in each barrel?

Each barrel holds up to 8 lbs of rock, grit and water combined. Fill roughly two-thirds full so stones tumble rather than slide.

Can I run one barrel at a time?

Yes. The two barrels run independently, so you can tumble one batch or split coarse and fine grit stages across both.

How long does a full polish take?

Expect about four to six weeks across coarse, medium, fine and polish stages. The 1–9 day timer lets you set each stage and walk away.

Is it quiet enough for an apartment?

It is rated as low as 35 dB, quieter than most belt-driven tumblers. Place it on a rubber mat on a solid surface to cut vibration further.

Does it come with grit and polishing media?

No. The kit is the tumbler and barrels only, so budget for a four-step grit pack and ceramic media separately.

How does it compare with a Lortone or Thumler's tumbler?

It offers more capacity and a timer for less than those metal-bodied brands. Lortone and Thumler's units are built for decades of use; the VEVOR is better for occasional hobby batches.

Our take on the VEVOR Rock Tumbler 8 lbs Double Barrel Rock Polishing Kit

The VEVOR 8 lbs Double Barrel Rock Tumbler is a direct-drive rotary tumbler with two 8 lb barrels, a 1–9 day timer, four speed settings and power-off memory. Its sealed barrels and overload protection suit hobbyists running larger batches of rough stone through coarse to polish stages. It is quieter than many belt-driven tumblers on paper, but the plastic barrels and simple build put it below Lortone and Thumler's rugged metal units for heavy daily use.
