    • Really impressed with the noise difference, seems really reliable so far
Perfect for those new to the hobby. If you are looking for the cheapest best option and this is it (there are cheaper but they are not the best). I wouldn't start with a model of any lower quality or with any less features than this one. They aren't kidding when they say its quiet. Honestly sounds just as quiet if not quieter than a modern dish washer or dryer. You could easily have this set up anywhere in your house and just hear a consistent hum. It's not grumbly and annoying either, its just white noise. The tumblers performance seems good so far, I am running sea glass through it now. I like that it has a larger barrel. It's wider at least which makes it easier to reach into and in my opinion allows the parts to tumble better because they have slightly more space to fall when they go round each turn. I haven't been nice to the thing, letting it collect dust and mud as I check things. It's held up to the grit and grime of tumbling. I'll clean it fully once this session is complete but I don't want to stop and clean every time so I'm just letting it go and seeing what it can take. The settings are simple to understand and the display is nice and clear letting you know exactly where you are in your process. I usually just scribble the info about what is tumbling on the front with a dry erase marker which is great with this enclosure. Another cool feature is it will keep the current time saved in the event of a power outage so you can just plug it back in and go. If you are just starting out, don't go with the $40 Walmart entry level kit they offer, upgrade to this one, it'll be well worth it. Buy once, cry once. Otherwise you will go through 2-3 of those cheaper models before deciding the noise is bothering you regardless of how well they work. Enclosed is the way to go. ... show more

    • Big yes
Yes, this is absolutely worth the price and is a great little machine. I am not an expert tumbler by any means, but this machine produces stunning results and is designed very well. I was very surprised by how quiet it actually is. We actually have ended up keeping it in the dining room and it is probably a little quieter or just less noticeable than the window unit a/c and dishwasher. It is kind of a calming white noise. The grit that comes with it isn't that great if you want really smooth and shiny, I bought that elsewhere pretty quickly. But the machine itself is very well designed and easy to use. It is the perfect solution for anyone that needs or prefers to tumble inside or doesn't have a lot of extra space ... show more

    • The best tumbler
I've owned one of these tumblers for almost 2 years now. I've changed the belt only once and had to tighten it only once. It's the most quiet tumbler out of the 5 I own. When needing a new belt, I was not only sent a new belt free of charge, but a gift with it. Customer service was remarkable. It's the easiest tumbler to clean between grit rotations as well. It's held up to so many polishing jobs in the last 2 years and still rolling them strong as ever. If my budget wasn't tight right now, I'd be buying 3 more of them. It's worth every penny. I love this Tumbler! ... show more

    • Very quiet, compared to a standard tumbler.
Works great! We've been running it in the living room it's so quiet! Wash well between cycles! There are YouTube videos that have better methods that the provided instructions. There are also supplier that sell the extra grit for a fraction of the price.

    • Burns out fast
Loved this rock tumbler for the first month or so, very quiet. I’ve ran though all stages only once, and on stage 2 of my second batch. It’s extremely loud and constant thumping. Tried removing rocks, cleaning, etc without luck. Ordered in July and now it’s junk

    • WORKS
We are tumbling our first set of rocks now. This is NOT like the rock tumblers that kids were given 40 years ago..... It runs very QUIETLY, and so far is actually rounding off the edges and the rocks, although still on first coarse sand setting are already rounded and looking good

I own a few of this rock tumbler now, I ended up loving it and so bought more. It's very quiet, the enclosed hood design also keeps my kittens hands out of it, and the barrel is built like a tank, so I never have to worry about issues with it, it's my go to one that never gives me problems. I wish more brands had barrels as sturdy as this. Customer service is absolutely amazing if you have questions or problems with anything, which will keep me coming back right there. The only negatives I have is the grit that came with it don't have a quality polish, but that's not uncommon in any brand, I just purchase a higher quality polish and use their polish as my extra fine grit for stones like quartz. Also, the stones that came with it were really crushed up, so that could be disappointing if you don't have any on hand and have to wait to get some to start tumbling. Definitely worth it. ... show more
