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

Works well and is significantly more silent than non-enclosed tumblers. Its very nice they include spare parts for some of the consumables (the rubber belts). My only suggestion is that the grit / polish it comes with probably should be somewhat different. The final polish is nowhere near the correct consistency. Generally to get a good shine you need something on the order of 8000 grit, not just 1200. Also you need a fair bit more ceramic media than provided. Also (nitpicking) the timings listed in the instruction book are way too short to get a good grind and polish on rocks. You need to opt to go much longer on the number of days of each level.BUT, in terms of hardware which is really what you are buying here, this is a nice unit. Expect to buy other consumables (grit and media) which is pretty normal anyway, and you won't be disappointed in the unit.

Very much enjoying the rock tumbler, and currently on the third stage of tumbling my first set of rocks. I received my second set of free rocks, and even received a third set because my tumbling kit was missing the jewelry mounting accessories, so Komestone made it right with additional rocks.Thus far, the rocks I am tumbling look great, and the product is solid. No issues, and the barrel is holding up well without leaks. I highly recommend this product.

Quiet tumble, and simply to work,, it's been running for 2 months straight and no issues, love this machine, highly recommend

I am a beginner and always wanted a tumbler... I'm on the 2nd phase of my first go round and I am really impressed on how quiet this is. It isn't totally silent but my shop is only 12'x20' and you can have a normal conversation in the room and its just a low background noise.So far it seems to be working as described and it takes up very little space which is a big issue in a tiny shop.Customer service is spot on and Lily is fantastic at responding to messages.Thank you Lily for your attention and a fun product foe me!

The enclosure keeps it quiet.Update on 10/26/24I’ve used it for a few weeks now. I am able to tumble more rocks at a time. This is very convenient. It remains quiet.I’ve emailed support with questions. They responded quickly. They gave me an answer with suggestions, recommendations, and guidance. This has been a worthwhile purchase

Design to seal the tumbler top seems well done, on phase 4/4-7days with polish. So far in the garage, out of sight and mind tumbling 24/7 sometimes we thing the EV car is running with the aC when going into the garage cause you basically set-and forget for 6 days per phase. I registered the warranty with this, and also got the free gift bag of rocks (we are currently tumbling the rocks we got from Manteca-great-wolf-waterpark-in the mining section-) and after the free bag- we plan to tumble any rocks we find on vacations. So far- it’s been a breeze to clean and prepare each set- I don’t know how many times u “twist” the final screw down- so just watch that- adult it doing that part do not over tighten or u can bend the metal/seal.We bought for the warranty and support and overall design/functions- we will see how it lasts over time. We had an old school (plastic belt) that broke. So I did like the drive belt on this one- it seems like it can be replaced- or a shipment part- the only thing that you need is oil lube- luckily I had some from my wife’s treadmill belt.One last thing- (I’m using old-corse-pregrit-pre polish-polish stage material from the one that broke above- so I have not used the ceramic pellets included- and u need to have a area you can “dump” ur grey waste in to dry out/throw away eventually. Kids buckets and a corner achieved this

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’s a beautiful machine, very quiet, Lily gives great tech,customer support, and follows up. Give their products a try, I think you’ll be happy. I am
