I had a problem and they sent me a whole outer unit. Works very well now. Easy to use and grandkids live putting their small river bed finds in. I like to tumble my jade for Indian jewelry. It is a little noisy but much quieter than my old tumbler. Feels very heavy duty. I have it in same room as my baby chicks who seem to accept it as background noise. Would buy again as gift. Review: Great customer care update - I give this a 5 star mainly due to Daisy in customer support. When the tumbler arrived it would not work at all. I was going to return it, but i noticed the great customer service reviews. Not only did I get a rapid response , but was given concise instructions on what to do. I took a video, sent it to Daisy and the very next day was told that the problem was determined it to be a faulty adapter. She sent a new one, which arrived quickly. I plugged it in and it has been running for the past five days without a hitch. Thank you Daisy. Time will tell if I can polish rocks or not. After using the tumbler for about two weeks, polishing rocks that had already been worked using another tumbler, I am thoroughly happy. Considering the cost I feel it is a great little machine. I must admit that I purchased some 8000 grit, and found it did a better job than the 1200. The tumbler is quiet, (I have it in my den), runs without a hitch, and is easy to use. The combination of great customer support, and a machine that does all I want, I would recommend this, especially to the beginners and young geologists. The rocks look better than my mediocre photos. ## Features - The FIRST and ONLY Noise-Reduction & Brushless Motor Rock Tumbler on the Market โ€“ Upgrade Your Rock Polishing Experience - 1 Year ๐–๐š๐ซ๐ซ๐š๐ง๐ญ๐ฒ- Special Bonus Just for You!

It seems solid and well constructed. I like being able to set the speed (3 speeds), and number of days to tumble. Itโ€™s not super quiet, but not too noisy. I have mine in the garage, and canโ€™t hear it at all from the house. They sent a bonus bag of nice assorted rocks to get started, and enough of the various grits of tumbling media to get started. ## Frequently Bought Together - KoolStone C1 Pro Max Brushless Rock Tumbler Kit - Extra Large 3LB Capacity, Up to 6X More Noise Cancelling, Ultra Quiet Rotary Polisher with Full Accessories, Ideal for Adults Kids - KoolStone Large Rock Tumbler Grit Kit [10 Pounds], Polish Up to [50 lbs.] of Rocks, 4 Steps Polish Refill Media Kit with [Ceramic and Plastic Pellet Tumbling Media], Compatible with Any Tumbler - 5 Packs of Rock Tumbler Replacement Belts, Only Compatible with KoolStone C1, C1 Pro & C3 Rock Tumbler, 78 * 4mm --- ## Why Shop on Desertcart? - ๐Ÿ›’ **Trusted by 1.3+ Million Shoppers** โ€” Serving international shoppers since 2016 - ๐ŸŒ **Shop Globally** โ€” Access 737+ million products across 21 categories - ๐Ÿ’ฐ **No Hidden Fees** โ€” All customs, duties, and taxes included in the price - ๐Ÿ”„ **15-Day Free Returns** โ€” Hassle-free returns (30 days for PRO members) - ๐Ÿ”’ **Secure Payments** โ€” Trusted payment options with buyer protection - โญ **TrustPilot Rated 4.5/5** โ€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/575279744-ultimate-edition](https://www.desertcart.pl/products/575279744-ultimate-edition) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-27*
