K2 Elite Professional Rock Tumbler Kit, Noise-Reduction & Cutting Edge Brushless Motor Rock Polisher for Adults & Kids, Ultra Quiet, Extra Large 3 Lbs Barrel, STEM Gift for All Ages

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.

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.

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.

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 recommend Thank you Komestone!

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
