Belts break easy and do not know where to get replacement because user manual is all in chinese

Very durable. The vibration caused it to walk off my table 2 times with no sign of damage. Takes a licking and keeps on ticking. I keep it on the floor now.

I’ve owned rock tumblers for many years. From cheap ones with plastic barrels that were incredibly noisy, to much more expensive ones made by Lortone. I’m pleased to report, the barrel on this one is comparable to the more expensive models. Consequently, the noise level is fine for use in a garage or basement.A unique feature is being able to program the length of the run cycle. Even my much more expensive models don’t have this feature.

Love it now I want a bigger one.

The directions were not very good. My daughters had to look up better directions and watch a couple videos and had to purchase a filler media so it didn't break down the rocks too much.

Power supply that comes with this unit is not for the United States, and there is no adapter included to make it work either. So it is useless to me. Needed it today for a project and it was one of the reasons I purchased it since it could be delivered the next day so I can complete what I was working on.

It brings out the rocks mineral colors very well

The media could not be loaded.  Easy to use right out of the box. Instructions were adequate to understand the process. I'm not sure a very small child would have the patience for the days and weeks that are required for the entire process unless this is a lesson in patience. An older, adolescent child or adult would be able to have fun with this.Comes with:Rock Tumbler, AC adapter, Bag of various rocks, Coarse grinding powder, Fine grinding powder, Polishing powder, Final polishing powder, Glue, a few jewelry making items. See pictures for everything included in the box. There are 2 types of rock tumblers: rotary and vibratory. This is a rotary tumbler. One thing I would like to point out that you'll need, that is not included, is some plastic or ceramic media.Plastic or ceramic pellets are used for cushioning in rotary tumblers. They distribute around the barrel and absorb impacts between rocks in the tumbler. That helps reduce chipping and bruising of your tumbled stones. It's really important for stones like obsidian and quartz that bruise easily.Plastic media must be stored after each tumbling step because it is really hard to clean. If you use plastic media in fine grit you can't use it later in polish because some of the fine grit might be carried along. Similarly, if you use it in medium grit you can't use it with fine because some of the medium grit might contaminate the fine step.With ceramic media, you can rinse it with the rocks and it stays with the rocks all through the tumbling process. The best choice is to use mostly large ceramic media because it will become small ceramic media after a few batches of tumbling. Now, with that being said there are lots of people that just prefer the plastic pellets so trying out both would be a learning step and might be interesting as a trial.Running easy-to-bruise materials like obsidian and crystalline quartz with 50% small media can significantly reduce the bruising that they receive in the tumbler. In the polishing step lots of small cylinders will brighten up your polish.Now for the tumbler itself: It is not quiet. Needs to be regulated to the garage or basement. See attached video clip. The motor seems good, runs well. It needs to be as you will typically run each batch for a week or two. Beginning with the coarse grit for a couple of days and switching out to medium grit for another couple days and then so on down to fine grit, polishing, etc. Each step is laid out pretty well in the little manual and if more info is desired a quick search on the web will deliver a plethora of information.You do need to be aware that this machine will need to run continuously for days at a time so if your electric bill is very bad it is a consideration. In doing a quick internet search I found this interesting info: If you live in Louisiana, the state with the lowest average cost of electricity per kilowatt hour, you will be paying about 6.9 cents per kilowatt hour. If you live in Hawaii, the state with the highest average cost of electricity, you will be paying a whopping 34.0 cents per kilowatt hour! On average, electricity costs of running a small rock tumbler in the United States is going to be about 10 cents per day or $3.00 per month. Please Note: This is an average for any small rock tumbler! NOT this particular one. You will need to do your own analysis if this is a concern.One additional item I'd like to mention is that the rocks supplied are not in any way identified. This would be a fun activity for a parent (with an older child) to do some sleuthing and identify the rocks. There are many, many suppliers online to order rough material from or plan a day on the beach for a rock hunt. Be aware that any glass you find and want to make your own "sea glass' needs to be at least 1/4" thick and about as big around as a quarter (or slightly larger). Glass that’s too thin will be worn away until there’s virtually nothing left. Thin glass won't work. Here again is where you'll need the ceramic filler we talked about earlier. Without filler, the raw glass pieces would smash into one another inside the tumbler barrel and become shattered or scratched.Do more research, plan ahead for your additional supplies and you'll love this new hobby. I would recommend this Rock Tumbler as a beginner's or hobbyist tumbler. Works very well, easy to put together and get started!

I bought two after receiving the first one! I found them easy to use, smart and well built. I particularly like the daily program features. The only con about this machine is the belts. They give you 3 but they do not last long, so I suggest taking one to an automotive, hydraulic shop and have them match the belt with a hydraulic rubber seal. Buy 2 or 3 of these and you will not go thru belts but very rarely.
