Review: Great rock tumbler for beginners or anyone looking for a quiet tumbler! - Very pleased with this tumbler, I am a beginner at tumbling and rock collecting for the most part, i love the easiness of set up and instructions, comes with multiple pendants/jewelry for making them. Also comes with 2 each pack of grits for each stage. May take about a month but I am so pleased with this item! The sound quality is very great as well, very quiet in my opinion, can’t hear it in the room against the garage either and it’s right against that wall! You really only hear it if you’re RIGHT out in the garage. For people who don’t mind a little noise it’s a great clicking noise I’m sure some people could even fall asleep to lol, it’s that quiet! The rubber really helps, the manual is super simple and has every single step especially for a beginner! I got the brushless edition because they are supposed to last longer and have better results I read online! Comes with extra belts, pendants, rock grits, 1lb of rocks (it was 15.4oz so just about a lb a little under but that is besides the point, they are very nice size as well. I love the size of the tumbler as well, it’s very cute. The durability seems great as well and it’s super simple, no mess ups! The speed adjusts as well, but follow the manual for best options on starting! It is very educational as well considering the manual is pretty dummy proof, perfect for beginners or even professionals! Functionality so far is great as well, will keep updated if anything changes. I read they have great customer service as well, so I’m very pleased!
Review: Good Product, Great Place to do Business... - We have made so many shiny rocks with our Tumbler since we purchased it. Gives hiking new energy to find rocks on the trail and such. When the motor had issues, the company was quick to respond and help get us up and running again. Nice to see customer service step up again. It has been a long time since i felt appreciated and truly taken care of by a company i do business with. Daisy was an absolute rockstar ! Many Thanks. Great Product, Even Better Company. People here make the difference.....Eric

### ⭐⭐⭐⭐⭐ Great Customer Service
*by K***R on August 20, 2026*

The motor failed within just a few months of use. I contacted customer service, the response was timely and they were able to ship out a new motor within just a weeks time frame. Exactly what a person expects when they make a purchase. I will definitely purchase from this company again.
