K2:Professional & Noise Reuction

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.

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

READ THIS REVIEW FIRST!! I often feel like I don’t get what I pay for when I order online. This tumbler is different!! It far exceeds my expectations on noise, (quiet enough for an apartment ), quality build, and included accessories ( extra drive belt, packs of abrasive, instructions, and even some quality minerals to start you out. Pull the lever. If you are determined to purchase a tumbler for lapidary or sea glass, you will be quite pleased.

First time tumbler just getting started and this is a GREAT tumbler to begin with! Clear simple instructions, sturdy unit, free rocks!! Each stage varies as to how loud it is, but I live in a small 800sq ft condo and keep it going 24/7 in my house. It sounds like a white noise machine to me! I had a little mishap with my lid (user error most likely) and reached out to the company. Right away they sent out a new lid AND more free rocks! They’re super friendly and helpful, and even followed up to make sure I received everything and check on if I needed any further assistance. Definitely recommend!

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!

Great little tumbler and I like that it is inside a case to make it a little quieter. My first batch of agates turned out awesome. Had an issue during my second batch and had to reach out to customer service. They responded right away and replaced the bad part immediately. They kept in contact to make sure everything was back in order. I am tumbling again!

I've been tumbling rocks since I was a child. I enjoy the process and seeing the rocks transform with each step. I've had several different brands of tumblers, but when I saw this one, I just had to get it. It's enclosed and cuts the noise down considerably. It also has a large barrel to accommodate more rocks. The instruction booklet has clear steps and tips to get the best results. The customer service is nothing short of amazing! They answered my inquiry of the machine walking around on my floor from the vibration. They followed up to see if my problem was resolved. Excellent customer service.
