I had already purchased 2 of these, and really love them. So I ordered another. Having 3 of these and set up in the garage makes tumbling more fun and speeds the process up a lot. These tumblers are built to last, but you must keep them clean to prevent any future problems. Would recommend these products.

The tumbler has been running non-stop sense It arrived. I have been using it to tumble rocks. It is not to loud. Does the job and can hold around 15 lbs of rock. Good buy

I couldn't figure out why people were so excited about wet tumbling, until I tried it. I can get my brass SO MUCH cleaner and brighter in 2 hours, than in 6-8 hours of dry tumbling.The cleanout and separating of the cases is a little more involved (using my bathtub as my kitchen sink isn't big enough) and takes roughly 10 minutes as opposed to dry tumbling, but the overall results are very impressive.I don't deprime first so can't comment on how clean the primer pockets would get. I love that I will never have to replace the stainless tumbling media or buy it again.By the time you load 8 lbs of water, 5 lbs of stainless media, that leaves about 4 lbs of brass. Roughly 500 9mmm, or 400 40SW (I'm a pistol shooter) which is comparable to my large Lyman dry tumbler.Need to give the tumbler a little 'push' to get it started, but then it just runs and runs. So much quieter as well, just the tinkle of the brass hitting against itself without the buzz that I could hear through the walls of my garage into my house with my other tumblers.Some great videos on YouTube to get you started. $250 for the tumbler and media and 2 hours and you have perfect brass.

Overall good tumbler.Some shortcomings to be aware of:1. It doesn't come with any kind of feet to sit on, no rubber pads, nothing. Seriously? We had to drill 4 holes to bolt on rubber feet, to keep it from sliding around the concrete floor while it's working. Seems like this should be a basic aspect of design, kind of ridiculous to have to do this yourself as the end user.2. Unlike some of the larger, more industrial tumblers that we use, this only has one drive roller. When the barrel is wet or somewhat imbalanced (depending on what you're tumbling), it can occasionally stop rotating. Dual drive roller system would've been preferable.3. No on/off switch. You have to plug/unplug the cord to start and stop it. Not a major issue, but just gets annoying over time, especially when other tumblers manage to incorporate an on/off switch.

I bought this tumbler about two months ago and have used it through one cycle of polishing. It is huge! I only put 7lbs of rocks in it with plenty of room to spare and then filled up the empty space to 3/4 with poly plastic beads. The beach rocks turned out gorgeous! I set it up in a tray in my bedroom walk-in closet and it was quiet enough to leave in there the whole time, although it’s not close to my bed area. I thought maybe I’d have to put it in the basement but it was perfectly fine. I noticed that if I added too much water to the mix it sloshed more and was noisier, so I took some out and it quieted down. It ran 24/7 without a hitch. No rubber wore off as long as I positioned it right on the roller. I am going to attempt a heavier batch next, 11.5lbs with room for the grit and plastic beads. I am going to use ceramic pellets for filler at some point, but they will add weight and I won’t be able fit as many rocks, but I’m doing some big ones and may need them to keep the rocks apart. I suppose I could also use a combination. It’s also important to burp the lid once a day because the heat from the friction causes a small vacuum and the rubber seal will stick to the inside rubber liner if you forget makimg it harder to get off. I will see how the machine holds up to more weight. I’m very happy with this large barreled tumbler so far.

Love this product. It runs smoothly and quietly. I have mine on a piece of flexible insulation (K-flex eco) on a tile floor on concrete. I say all of that to say that it is almost silent, you can barely hear the rocks tumble. I had it directly on a wood cabinet and you could hear it 50 ft. away. So if you are having problems with the sound I would just change the location. It is built out of very thick steel and around 1/4 in rubber as the lining. The lid has a little bit thinner rubber, and wing nuts that are easily replaced at your local hardware store, but mine haven't worn out. I may post some pictures of polished rocks, but don't really see the point they are indistinguishable from ones that you can find at a souvenir shop. The motor is pretty cheap (I am an electronic technician), but built rugged, so although it is single speed and not very efficient it should last for years as long as you keep the dust out. The belt on mine hasn't worn at all after several months. The only parts that have seen any wear are the red paint where the drum sits on the drive shaft (from getting grit on it after changing to a finer grit), and the rubber guide piece on the drive shaft where it keeps it straight.

This Tumblr works great for polishing the brass parts of Clocks and their cases.
