Ultra Quiet Rock Tumbler Kit for Adults – 3LB Professional Rock Polisher with Noise-Reduction Cover & Brushless Motor, 3 Speeds, 9-Day Timer & Complete Accessories for Hobbyists & Collectors

This is great for beginners and avid rock hunters . My wife and I just started rock hunting last year. You can turn your finds into beautiful art. We are very impressed on the sturdiness and ease of use.Assembly was easy, It comes with easy follow instructions just take your time if you are a beginner. It comes with a nice assortment of rocks and plenty of product to get started, the controls are simple and instructions are clear even for a beginner, appears to be well made. It is very quiet for what it does . Nice size for the different stages of tumbling rocks.We have found that doing multiple batches in the different stages then combining them as the rocks reduce in size that way you are not wasting polishing grit. Rock Tumbler well packed for shipping and reasonably priced.

I’ve been running the K2 Elite nonstop for over a month, and it’s been rock solid. It works exactly as advertised—no issues, no stopping, just consistent performance.The biggest standout is how quiet it is. The rubber barrel and enclosed housing make a huge difference compared to other tumblers I’ve used. It’s more of a low hum than that loud rattling noise.It came with extra belts, but I haven’t needed any yet, which says a lot about durability. Build quality feels solid, and the 3 lb capacity is perfect for decent-sized batches.Customer service has also been excellent—they respond quickly and are actually helpful. They also send a free bag of rocks on top of the bag that came with it, you just have to email them.Bottom line: Quiet, reliable, and well-built. Definitely one of the better tumblers I’ve owned.

I love this tumbler. I haven't had any issues with it since it was bought and I have been running it nonstop. I like that the belt is in a compartment to itself so it doesn't spin lubricant everywhere. You should keep your belt lubricated with a 3in1 oil or clipper oil so they don't dry and break. It's a little quieter than the ones that are out in the open. But it still going to be somewhat loud, it is tumbling rocks. It's durable and seems to be holding up. The barrel has a good thickness to it isn't showing any signs of wear and tear yet. I do like that it has a 3lb storage capacity. It holds a lot more rocks than the other small rock tumblers. It does come with some starter rocks and if you reach out to them after purchasing they will send some free rocks as well. I do believe it is a good value for everything that came with the machine. I think this tumbler is a good addition for any person that is interested in rock tumbling.

I got the K2 Elite setup and it's perfect! First tumbler I've ever owned it it's exactly what I needed. I polished up some stones to get the feel for it, but then deburred some small aluminum rings and it handled both jobs perfectly! It's very compact, but also has a large barrel for things. Clear window in the front allows you to see it turning and tell if it's leaking, or if anything else is going on. Accessories that came with it are perfect, too. Emailed them immediately after getting it and within a few days, had myself another bag of really cool stones to polish up. Great communication. Great product. I've used it quite a bit since getting it. I would definitely recommend it. Especially to a beginner who doesn't know a lot about tumbling(like I was). Walks you through everything and makes it all very easy to understand so that you can get right to work.My only slight complaints would be that, it's not actually silent. It definitely makes noise. My wife and I do not run it overnight because of this. But, that's not a really big deal.Also, the amount of ceramic medium that you get is rather small. I ended up just buying some similar stuff from Amazon and have been using it. Once again, though. Not a deal breaker.Overall, great machine. Great price. Does its job. Easy to use. Compact. Versatile for multiple applications.I was not paid for this review. I didn't get the machine for free and am not getting compensated in any way for the review. I just really like it.

It works great! I love the automatic shut off feature when the set days of tumbling is over. I also loved how it is encapsulated. It helps with noise, but it still is quite a bit noisy. It is not quiet enough to leave in a room that you want to be in. It has to be in a separate room with the door closed. It also needs some antivibration feet placed beneath it since it rumbles the wood floor a lot. If you have a concrete floor, it is not needed, but it vibrates the wood floor a lot. All in all a great tumbler!

I purchased the KomeStone K2 Elite Professional Rock Tumbler as a birthday gift for my husband, and I couldn’t be happier with my choice. The machine feels sturdy, professional, and well-designed. The instructions are clear, and the kit comes with everything you need to get started.What impressed me the most, however, was KomeStone’s outstanding customer service. They were kind enough to send me an extra bag of rocks as a gift, which was such a thoughtful gesture. They even followed up by email to make sure I received everything. That level of attention and care is rare and truly appreciated.We have already opened the tumbler and it works perfectly smooth, quiet, and exactly as described. I’m very excited to see the polished stones after the full cycle. Highly recommend both the product and the company! :D 10/10

I recently had the chance to use the Rock Tumbler Polishing Grits and Ceramic Tumbling Media Kit, and overall, I was pleased with the products. This kit comes with all the necessary components for achieving smooth, polished stones, including a complete set of high-quality polishing grits and ceramic media. Each step comes with an ample amount of product for probably over a years worth of rough rock tumbling, and I'm excited to put it to use.Pros:• Comprehensive Kit: It includes all four stages of grits (coarse, medium, fine, and polish), making it a one-stop solution for rock tumbling enthusiasts.• Ceramic Media Addition: The ceramic media helps cushion the stones and assists in achieving an even polish, which was noticeable in my results.• Quality Finish: The polishing stage left my stones with a bright, glass-like sheen that exceeded my expectations.Cons:• Portion Instructions: While this kit comes with two scoops you will need to know the portion sizes you need for your tumbler because there are no instructions for this.Overall Impression:This kit is a solid choice for anyone looking to achieve professional-quality results in their rock tumbling projects. The grit quality and ceramic media significantly enhanced the outcome, making it well worth the investment for hobbyists and collectors.Would definitely recommend it to those looking to improve their tumbling process and achieve high-gloss, polished stones.

Tumbler seems well designed. Controls are easy to use and program. Operation is smooth and quiet - the enclosed cabinet design reduces noise level drastically. It's quiet enough to use on a spare table in my kitchen. Having fun so far running my first full load of stones.

I bought these refills after purchasing my rock tumbler and the size is amazing. We have tumbled 4 more cycles of rocks and it’s barely made a dent in the refills. This is a great value!

My new tumbler is so much fun and I’m already on my second round of stones being polished. However, I had to pause for a small issue with the lid, but after reaching out to [email protected], they resolved my issue immediately and were incredibly kind and supportive. They worked fast to send me a replacement lid and the tumbler is now back in action!I’m so excited to see what my next batch of stones will be like (turning finds into jewels!).As for the tumbler, it runs very well and sturdy, no leaks and isn’t too noisy, though I keep it in the basement anyway!I really love how easy it is to set the amount of days and speed and the instruction booklet is great for a first time tumbler like myself.I’m very happy with this purchase.

There were no surprises all was as it should be 😁

I absolutely love my Komestone K2Elite professional rock tumbler! It is super quiet and super simple to use! It does an amazing job shaping and polishing my rocks! I have mentioned and recommended this tumbler multiple times in all of my Facebook rockhounding groups! Now that I have 1, I am realizing that I am realizing I could use another so I am able to tumble more than 1 stage at a time. Slowly but surely saving for another!10/10 definitely recommendThank you Komestone!

It was great that the grits came in hard plastic containers, they even had a plastic reusable cover inside the lid, it helps make sure no loose product in the lid. Better deal to buy these than individually.
