with my "old" (2 years) device had suddenly put the sealing ring around the blender knife, this blocked and thus completely sanded the essay by. the decision was here, either the attachment directly from mr. order magic or this complete set for not much more. I opted for this great set, because if once again slipped a sealing ring and what destroys, I definitely still a replacement blade / cup / lid / mixer (have the old still keep). you can with this device, puree, chop, mix, etc., ice / frozen it should also create, but since I do not trust even ran me. Personally, I use the device every morning to give me my smoothie making, the device is not exactly quiet, but then you should run it at a time anyway no longer than one minute, which is still to be absorbed. My neighbors have (so far) not yet complained. there are 2 different attachments, a sound with 2 and go one better with 2 additional projecting sound, so is the crush. Unfortunately it creates the device is not spinach or broccoli, etc. really fine crushing. which creates in this price range but no mixer. the really great thing about this is here, too, that is mixed directly in the cup, you simply turn the lid on it and you can already take his drink. to clean the top is not easy, because you can not separately take out the sound.
