This is the second of these that I purchased. I'm using them to tumble rocks in stage 1 even though this is designed for light weight cleaning tasks... coins, jewelry, etc... Still, it makes for a very inexpensive rock tumbler compared to machines built to tumble 12lbs of rocks. This has a decent DC powered motor, but the conversion circuitry (from AC / mains power to DC power for the motor), seems to be grossly inefficient..... which is where my title comes into play..... With a total barrel weight of 9.8lbs (empty barrel + rocks + water + grit) this pulls a LOT of power from the AC outlet, using about 4x the electricity of my 3lb tumbler overloaded to 4lbs. It cost me about $1.50 per day to run it from AC plug in. Upon noticing that it has a DC motor, I converted my first one to run directly off 12V battery - NOT RECOMMENDED unless you have professional training in AC and DC electrical systems. As soon as this one arrived, I also converted it to run on 12V battery with a voltage rheostat to control the RPM's. My battery will run one tumbler for about 228 hours, nearly 10 days, and then costs about $2 to recharge the battery to run another 9 days. Running both tumblers at the same time dropped me down to about 98 hours runtime. Unfortunately, I didn't think to plug this one in & test it out before converting it. It has a bad motor, which was only evident after turning on the auto-reverse feature after I had already converted it to run directly off battery. It runs fine forward, but when it reverses, it doesn't run well at all, to the point of coming to a complete stop two days after the conversion, then won't run forward or reverse... The motor is getting slightly warmer than the first unit I bought, at about 115F, the original one only gets to about 100F right next to it. So it's not due to overheating.... Seems like just a bad motor. I primarily got the second one for the new barrel anyway. After 12 months of almost continuous tumbling, the original barrel is starting to wear out. It still has quite a bit of life left in it, I would guess that it has at least a another 12 months of tumbling before it wears enough to be trashed. All-in-all, I would recommend this tumbler, just make sure you check it out pretty well as soon as possible.

La maquina funciona correctamente peor las bolitas que vienen con ella se me oxidaron ya en el prime uso. Son de muy mala calidad. Al final hay que comprar otras

It works as it should. I had some issues with the motor at the beginning As it just suddenly stopped. I think an internal safety switch must have tripped as it suddenly started working again the next day. Only down side is the clear plastic is pointless as it soon scratches up and you can't see anything

Maskinen fungere fint,men de medfølgende kugler er rigtig ringe rustfri kvalitet, så ruster og misfarver emnerne. Bruger maskinen til at rense 9mm patron hylstre.

Great machine so far. No problems and i am enjoying using it. If the beads were better quality i would of given it 5 stars.

Very noisy. 1st speed is still too fast. Tends to run off the drive wheels. Must use water to keep a balance. Still runs off the drive wheels. Steel balls are a pain to remove from the drum without a magnet.

Well made and works very well. Have experienced some minor electrical switch issues but these were easily fixes. Has done many hours work now tumbling rifle brass with great effect.

Overall this tumbler works as it should. The only negative is that level one is actually really fast. A little too fast that I get worried it’s going to damage some of my Jewellery. My old 3 kg tumbler from vevor had a much slower level one which I preferred. The level one on this machine is more like a level three or four on the old vevor tumbler from years ago. Apart from that it seems solid and works good. I do like that the opening of this one is bigger than the old vevor one. I bought this one to replace my old one which finally died on me, it lasted a good three years though so I have no complaints.

J aurais du prendre la 5kg c est un peu juste la 3kg Au top.livraison rapide sinon je recommande Vous pouvez acheter une équipe sérieuse

It works well, but you need a lot more polishing media than what is included. You should fill it 50-60% full, so count on buying 2 kg steel shot. It is a bit fast for dry media, walnut tends to not tumble but go flying a bit. You want the media to ride up the side of the barrel and then slide down to the bottom. Filling 50-60% gives the longest “sliding hill”. If the parts fly and hit each other they will dent, so a tumbling/sliding action is what you want. You can put smaller drive wheels on it to slow it down. I have a lathe so I turned them down. There is still enough speed when you load it up with heavy steel shot. If you tumble delicate or rare items such as coins you might have to tumble only one item at a time to avoid all possible damage by parts hitting each other. All in all a very good buy for the money.
