  • Advanced Brushless Motor – Faster, More Powerful, Built to Last: Unlike traditional brushed motors, the C1 Pro Ultra’s high-performance brushless motor delivers smoother rotation, lower heat, improved durability, and more consistent polishing results over long tumbling cycles.
  • Dual-Barrel (3.5 lb × 2) – Tumble More in Less Time: Polish twice the amount of stones, run different grit stages simultaneously, or separate materials with ease. The dual 3.5 lb barrel system increases efficiency while reducing total project time.
  • Ultra-Quiet Operation – Designed for Home Use: Featuring premium rubber barrels and a noise-reduction housing, the C1 Pro Ultra operates far quieter than traditional plastic tumblers—making it ideal for apartments, hobby rooms, and overnight tumbling.
  • Smart Controls for Easier Tumbling – Features 4 speed settings, a 9-day timer, auto shutoff, memory function, and an exclusive Cycle Record Button to help beginners stay organized throughout every polishing stage.
  • Complete Rock Tumbling Kit – Everything You Need: Includes the tumbler with two 3.5 lb rubber barrels, 2 lb of rough gemstones, 2 belts, 8 types of polishing grits, ceramic pellets, sifter, mesh strainer, jewelry fastenings, and a step-by-step guide. Worry-Free Support: 12-month warranty, lifetime customer support, plus detailed setup videos and FAQs.
