Tumble-Bee Rock Tumbler - Single Tumbler for Adults and Kids - Rotary Machine for Stone, Rock, Metal and Sea Glass - Polishing Machine Kit for Professionals & Hobbyists - Model TB-12-KIT

My 6yo and I just wore out our first cheap 3lb tumbler so I 'upgraded' to this one . Main reasons being it has slightly more capacity and has cheap available parts. A 1$ gasket wore out on the old one but you can't buy just the gasket they want you to replace the whole barrel assembly. With this one I checked the website and you can order replacement parts individually for cheap.Added bonus it is a little quieter than the last one. Still keep it in the garage but it's not super loud.Another added bonus is it came with 3lbs of what look like pretty neat little rocks. We have no shortage of rocks but it is neat that it comes with all the rocks and compounds you need to get going .Will update if anything changes but rn it seems nice to me. Basic beginner/kid rock tumbler.Update- Oct 2020. The tumbler broke after a few batches but at least parts are cheap I guess

This thing is great. Just keep it lubed properly. I remove the shafts and use moly lube rather than plain oil. It is going over a year old and still going strong. We are now going for a bigger machine to do bigger rocks. We've learned much from this one.

+ It has only one speed and runs slowly - 40 spins per minute. It is gentler for fluorite, howlite, and other rocks with a lower Mohs hardness.- while it runs okay, it produces a lot of black rubber debris.- sometimes, I have to adjust the knobs on the left side to make the belt move.- it only lasts for four weeks.

My son (a geology major) loves this tumbler. He has had it running non-stop since he got it for his birthday in SeptemberThe only thing I would recommend is a small fan to evacuate the heat the motor produces. There is a small fan built into the drive shaft, and the housing has vent holes. The housing still gets rather warm. I installed a small computer fan onto the outside pulling the heat and the temperature has dropped significantly to the touch.

I like to wait until I have used an item for a period of time and then write the review as it gives a more accurate accounting for the item. I purchased this rock tumbler in March of 2020 and it is now close to one year since my purchase. I have had my tumbler going for basically one year non-stop and it is working just as it did when I first started. I have had to replace the Gasket Seal in the lid once in this past year. The barrel started to slip and not turn after several months of use as the drive shaft that the barrel sits on got polished itself and the barrel was slipping. I took some course emery cloth and roughed up the shaft and the barrel started to roll again. The weight limit suggested is too high and if you put in the suggested weight limit, the motor might over heat. All in all a good quality product that I am happy with

Tumbler has shown to be good. It is sturdy, good quality, easy to use, Not too fast speed, Medium size. It's been running steady for several months.

This is a great tumble better than our first national he one . Good quality!!!

I really like it, had to readjust the belt after it came, but no big deal.
