Item works very well , as far as rock tumblers go this is very quiet compared to many units. Enjoy 3 speed separation for the different types of stages for tumbling also 9-day timer. Barrel is also well made very durable , lid twice as thick as some units . Customer service is 100% they will return your call within 24 to 48 hours during business days . You can expect a good experience with this product I was not paid for my comments this is an honest opinion of product after using it for several months . Also the 4 step kit with additional ceramic media is an awesome add to this complete set up ,items work very well you will be pleased with your investment.

I’m giving it two stars because it is pretty quiet and seems well built. But since receiving this unit, I’ve tried to run it for a week and it just keeps turning itself off. Sometimes it runs for a few hours and sometimes it runs for a few minutes, but it will not stay on. It seems to be something to do with a tip sensor. If I barely tip the unit forward while it is running it will immediately power off. So I’ve tried to stabilize it snd slightly prop it up but no matter what I do it will shut itself off eventually. I would recommend purchasing a tumbler from a different brand.Edit: After speaking with the company, they sent me a replacement base and it works much better. It has stayed on for two 5-6 day tumble stages no problem. It does still vibrate out of place and will walk over the course of a few days, but putting something heavy in front of it stopped that. Changed my review to 5 stars.

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.

Edited review: So I just got email from Ann asking me to make another update or review. The extra stones they promised you can get after receiving the K2 Tumbler is good. The stones arrived last week and I have been tumbling some them in my new K2 Tumbler. It is quieter than the open ones. They kept their word and sent out the extra rocks and they looked great. Waiting to see how they come out after the 1st stage is finished. Thank You Ann for keep in touch and yes I got the Rocks. I like this company. Will order more things from them in future. If you buy the K2 go ahead and get the extra rocks they will send them. No joke. Ok hope this review helps anyone wondering about that. Peace.I just got my new Tumbler the K2 that is enclosed and is truly quiet compared to some others I have seen. Have not tumbled any rocks yet. I sent email to the address on the card inside the box when it arrived to see if they really will send me more rocks for free as a gift. They replied same day telling me they will arrive 5-7 days. They are keeping their word regarding this. I will update my review when I get some rocks finished and use the tumbler. They said to oil the belt on the motor so I ordered some Singer Sewing Machine oil to put on it before tumbling any rocks. It arrived without any damage. The support team I heard from are Anne & Grace. They have been very helpful so far. Give them a try. I like this company so far and their support people. Wish them and you a very good day. Peace.

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

I’ve been using the KomeStone grits for 2 years now, and it has exceeded my expectations. This works perfectly with my rock tumbler. Each stage’s grit is high quality and produces a really nice polish. The ceramic tumbling media is a fantastic. They are durable and last forever!It is a great value. The kit lasts through multiple round.After just the third stage, I was already seeing some rocks come out incredibly shiny, almost good enough to skip the final polish! They had a smooth, glossy look that really brought out the colors. But going through all four steps made the final results even better. Even some of my rougher stones came out looking like they’d been professionally polished.If you’re looking to have fun with rock polishing, this kit is just perfect!

I’m really enjoying this tumbler. I had one for many, many years and decided to get a new one. Works great and the manual is well written!

He loves it and he started up right away with the explicit instructions. Very professional and is not too noisy as advertised.

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!

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.

Great starter kit once you understand the rocks that come with it are different MOHS and don't all play well together. The booklet does warn about this but I ignored it, not understanding that rocks can get bruised because of this. Subsequent batches have turned out well.
