Ultra Quiet Rock Tumbler Kit, Professional Brushless Motor & Double-Barrel for 7 LBS Capacity, 6X Noise Cancelling Rock Polisher for Rock Collectors with All Accessories, Ideal Gift for Adults

I jumped into tumbling with no idea what I was doing, and I made a lot of mistakes, initially. The first of them being buying a tumbler from Temu. The Komestone tumblers are a huge upgrade from that! The barrels are very sturdy and well designed. I have had no issues with leaking, and they are very quiet (aside from the rocks tumbling around, obviously). I like having a timer to set for each stage, as it saves me the hassle of having to make notes or hopefully just remember. I didn't honestly follow the instructions in the booklet. Instead, Michigan Rocks on YouTube has really good instruction videos, and they're very helpful. This hobby requires a lot of patience, and that's probably the most important lesson I've learned. And while this brand's tumblers offer multiple speed settings, I've never used anything other than 1st speed. Many more experienced tumblers recommend a speed of around 40-45 rpms, as a more gentle tumble helps prevent damage to the stones. The 1st speed on these is faster than that... and yet, I still get results I'm happy with. These are good machines. I own two of the single barrels, and one double barrel, and I love them. I have found their customer service to be quite responsive, as well. There is so much to learn in this hobby, but it is so rewarding! It's important to keep an open mind, do your research, and ultimately to just have fun and enjoy the process! Would I recommend these machines? Absolutely!

Don’t waste your money because by the time you realize it’s a total piece of crap it will be past the 30 days and is too late to return. You will go through belts like crazy. So then they will send you a kit to rebuild the belt system, but it only makes it run like crap, overheats and shuts off. It will only spin one barrel half full an makes it Hella slow, on the highest speed #4 it only spins about as fast as speed #1 on my single barrel one. It’s definitely a certified P.O.S. Needs a bigger motor and or bigger belt pulley system to operate correctly that would make it an awesome lil set up.You’re better off buying 2 single barrel ultra quiet units they work great I highly recommend. I have owned one longer than this double barrel and have had no problems with it at all

It works well, however the noise level is not as quiet as I expected it to be.

If you're new to rock tumbling and you do enjoy tumbling your stones you probably would like to do twice as much product Don't look any further this product is awesome It has the BEST BARREL'S & LIDS on the market double insulated The lids are twice as thick as any other ones on the market for a beginners value , also has brushless motor design which is twice as reliable as a brushed motor and twice the longevity , well built unit for the price . Unless you're using a professional machine this will fit all of your needs usually the professional equipment cost at least twice $349.00 as much to start , if not three times as much $700.00. At that level it's a completely different ballpark.

Very disappointed, I didn’t even make it through week one before they stopped rolling. It got very noisy, and then stopped rolling all together. Belt is fine just won’t move…..

I have ran a 4 week cycle through the tumbler. It did require a pully kit and different belts to get it going. It works well and is not very noisy. I feel that it well worth the investment.

This machine is not capable of a full load of rocks . I put more rocks in my small machine. The machine does not stay running.i give this product no star.
