I like the unit, it does what it is suppose to. The only thing I don't like is the two screws that hold the cover down they rusted within two weeks. What I found is that the tumble media is very important on what is being done. I can now clean my coin purchases very quickly taking many many days off the process. I am thinking about buying a voltage timer for it to run at longer periods and shut the unit off automatically.

Menos por las bolas de pulido con las que viene esta máquina (que dicen ser de acero inox y no lo son)... La máquina funciona estupendamente. Recomendable.

I have cleaned lots and lots of brass cases for reloading. Works well, but I would prefer stainless beads as the delivered beads will rust if not dried carefully after use.

Sportello di ingresso piccolo rispetto al volume del recipiente ma funziona bene

NICE

I'm a stone tumbler and this machine is one of the best tumblers for small stones up to 6cm. The problem is that it's hand cranked every hour. So I'm continually having to crank it.

Robust and good product, the main problem is the far too short timer ...60 minutes is far too quick...in conclusion I didn't enjoy constantly turning it on to get decent tumbling time.

Satisfait de mon achat livraison rapide, prix correct et fait le job. Toutefois et raison du 99%, les billes ne sont pas en inox et tachent le cuivre lors du nettoyage. Elles pourraient être remplacées et livrées avec par des pins inox.

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.

Contant dans l'ensemble de mon achat pour le moment. 2 points à améliorer : Les perles fournies rouille Un moyen d'isolation dans le tumbler pour que cela fasse moins de bruits.
