I bought this from BuyIndiankitchen.com, and I have been involved in a raw food course and this melanger is the one they use to make raw chocolate plus nut and seed butters. When I first used it I was a bit frightened of it because it is quite heavy. Also I had not tightened the knobs on either side properly and when I switched it on the drum tilted forwards. Fortunately it was empty. Anyway, I have now used it for chocolate and nut butters. I really love this machine and think it is very reasonably priced compared to some I have seen. It is quite noisy but not at the level of say a food processor or blender. I have left it on overnight and could hear it upstairs from one room (my house isn't the biggest in the world) but I'm not doing that all the time. It is a heavy item and you need to be mindful of that all the time I think and be careful washing it. Having said that I am really happy with my purchase and would recommend it. Also arrived in super fast time considering it came from India.
