Rock Tumblers Kit - Includes Rough Gemstones, 4 Polishing Grits, Jewelry Fastenings,Operating Instruction, Great Stem Science Kit for Kids

I ordered this to replace the one that I had that replace the first one. This one is not as quit as the other ones. But it works great.

Love this! Super easy to use and easy to follow instructions. Good speed, isn’t too fast to bruise rocks as long as you separate by hardness and follow instructions. Comes with starter rocks in a nice selection, grit, and has been a fun start to a new hobby. Balanced weight well with 2 canisters running and so far my tumbled rocks are turning out smooth and good looking following the provided directions.

The media could not be loaded. This seller stands behind their product -- which was good to see after I was forced to leave a 1-star review as my only way to reach them. They responded quickly to my initial review, offered a full refund of my purchase price (which I have since received). I said that I would change my review but that they had to take the model off of the market and make my suggested improvements. The fact that this seller reads reviews of their product -- and, encountering a bad one, responds quickly says something positive about the seller.Here is what I experienced -- along with my suggestions to improve the tumbler.1. The Seller needs to make it easier to contact them -- and can start by including, at a minimum, an email address.The email address needs to be included in the manual and on the customer service card that came with the tumbler. Contact information should also be readily available on the product page and the seller's page. When I ran into trouble with the tumbler and wanted to contact the seller, nowhere -- and I mean _nowhere_ -- on the tumbler, the manual or their seller's amazon page is a phone number, email address and/or website listed. (Their documents implore you to reach out to them if you have a problem -- but provide no means to do so.) I even called amazon customer support for assistance contacting the seller -- and they were unable to assist me!2. When on a level surface, the tumbler needs to have more effective means of keeping the barrel on the rollers and from migrating backward and forward and thus rubbing against the tumbler.Why? Because from the beginning, when the tumbler was turned on, the barrel would migrate toward the back of the tumbler despite the tumbler being on a level surface. The barrel would scrape against the 2 metal plates that are protecting the motor and belt mechanism; this caused damage to the bottom of the barrel. Since the tumbler seemed otherwise solidly constructed, I solved this problem by elevating the back of the tumbler. This worked for about 9 months -- except that I had to keep elevating the back of the tumbler more and more. At month 10, the barrel started skipping and making a horrible sound -- and despite the incline or whether the barrel was empty or had rocks in it, the barrel kept moving backward in the tumbler. Then it started jumping (see video) -- and making more odd noises. As you can see from the photos and video, there was plenty of damage to the barrel and tumbler.3. Make the belt easy to replace -- and include detailed printed and video instructions. (It is very rare that a tumbler comes with so many replacement belts. This one came with 5. Kudos to the seller.)Continuing my story: At this 10-month point, I thought I'd change the belt. Instructions for changing the belt, video or otherwise, were not provided. But with a full parts diagram included in the manual, I thought I would try to replace the belt. This ended in failure: after carefully and slowly taking things apart, I got to a point of realizing that there was no way I was going to get the tumbler put back together properly. I then looked for a way to contact the seller -- and found that the only way to reach out was to leave a review, one that accurately reflected my experience.Again, there are things to like about this tumbler: it is fairly quiet compared to 2 others I own; the construction is solid; the tumbling speed is really good (most tumblers are much too fast, even on their slowest speed!); the tumbler has 1 on/off rocker switch and no other controls and I like this simplicity (if the power goes out the tumbler will come back on with the power); it is a good value for the money -- even better if the seller uses my input to improve their product and service.

Machine seems sturdy. It is quiet and seals up very well. Problem: Even with the end raised 1/2 inch, the barrel moves uphill until the bottom of the barrel rubs against the cooling fins located above the motor. It will not stay centered in the Barrel well. In 3 hours of running the bottom of the barrel is noticeably worn.

Bought in January 13 2024. Been running ever since. No issues. Oil after every batch change over. No issues with belts. Still running original belt. Best little machine. Runs round belts. Not the tooth belts. Better upgrade from my Leegol brand. That has been a pain from the beginning. I'm very happy about this purchase and gonna be getting a second one.

The machine is very nice but the barrels wore out and under six months I went ahead and bought the big dog 40 pound rock Tumblr. I think it was about $500. I love it very much.

Excellent, I use this tumbler for etching lass beads and it works great. Quiet enough, and excellent price,

It seems like a pretty good item at first glance, but it has many flaws. I am just getting into rock tumbling and I purchased this after using a single tumbler for about a month, thinking it would be efficient to run three tumblers simultaneously and have three batches going all at the same time. The stones that came with it are really nice, but other than that, this product hasn't really lived up to my expectations. It arrived in poor shape. The movement of the package (I think) caused the rod to come loose. I didn't notice how much of a big deal it was until after the first day of tumbling. I had to remove the cover and fix it. I would definitely recommend lubricating every moving part frequently, as it helps with the noise. The noise isn't an issue for me at all because I use it in an insulated garage and you cannot hear it from inside the house. I've been using it for a few days now and I will make it work, but I regret choosing this item over other listings. I did not realize you cannot set different speeds. My other tumbler has three speed settings. It appears to only rotate at the same speed as the middle setting of my other tumbler. Oh and also one of the tightening knobs is very loose on one of the drums. I really don't see this lasting very long for me.
