Englischkenntnisse vorausgesetzt. Mit im Paket sind tatsächlich schöne Steine, wie Lapis Lazuli oder Tigerauge. Den Medium-Schritt kann man überspringen, wenn man den Course(Grob) einfach ein bis zwei Tage länger laufen lässt. Ja, TAGE. Polieren dauert bis zu einer Woche, aber es reicht, das Gerät Tagsüber laufen zu lassen, ist auch sicherer. Darüber hinaus kann man einfach grobes Silizium-Carbit und Aluminiumoxid kaufen und jederzeit schöne Steine selbst polieren. Trommel ist aus Gummi, daher ist sie nicht ganz so laut. Bedienung ist ein Kinderspiel. Read more

This is a great introductory rock polisher and does an excellent job. The manual could include more tips on practical rock polishing. The supplied rock mix contains various types of rocks that in some cases should not be polished together as the softer rocks are destroyed by the harder rocks. That being said it is part of the learning experience. Please note the machine is noisy and may need a sound proof box unless you have a shed some distance from your home. Read more

There are 3 versions of this, the 'toy', the hobby version (this one) and pro version. The pro has a speed control and bigger drum. One thing I have consistently read is.....ignore the supplied instructions. I looked on YouTube and "Michegan Rocks" does a great set of instructions. Basically, the starter rocks are not quite big enough in volume and supplied grit is nowhere near enough. If you really want this to work, it'll take about 6 to 8 weeks with an additional cleaning step so be prepared to need to order more grit, polishing compound and borax/Ivory soap. That way, you are in better stead to get a high quality shine. If you have the time, this'll work a treat. I'm retired so I've got nothing but time. I have this running right now in an upstairs spare room with the door shut and I can't hear it running too much at all but I'll turn it off at night. Very happy with the build quality. Now it's experimenting time! Good luck and don't expect overnight success. Great bit of kit. Review addendum after stage 1: I've added some pictures of the highlights AFTER my stage 1 tumble. The others are BEFORE. I think the result, so far is pretty good. Couple of things. The rocks provided was small in number and on the small size so some little shards are really small. At the moment I'm really just getting a feeling of it but I have to say, I am really pleased. I've ordered some more stage 1 and 2 grit as after 1 more day, I'll be moving to stage 2. I think more rocks and of harder persuasion will be the real test but results so far are well worth the wait. Great bit of kit. Read more

It is incredibly loud. There is no place in my house that I can run this overnight. I live in Canada, cannot leave water in unheated shed. There is enough abrasive material for one tumbling cycle. The cycles take 3 - 6 days each. Many of the included rocks are so small, they are unusable after the 2nd or 3rd cycle. This product could be better. It does exactly as intended. My son is more knowledgable since we purchased this product. Read more
