I am pretty disappointed with this product. I bought this product because it said it would automatically turn off after the water was gone (about 6-8 hours). That would be the case, but the actual chamber never completely empties...mine ran for 11 hours straight before I finally turned it off. Once the chamber gets to 1/4 or 1/5 full, the vapor mist stops coming out...thus the water is stuck. You therefore are wasting good quality oils. I was really excited about this, but am pretty bummed.

I purchased this blender based on its high rating from a well-known consumer magazine. I usually this magazine's ratings, but it really let me down on this one. As others have noted, the blender is high powered enough, but terrible for making smoothies - the main reason that I bought it. It just throws the chunks of food to the sides and top, preventing it from chopping up pieces small enough. My old, simple blender did a much better job. When I called Ninja beyond the 30-day Amazon return window, they would not stand behind their product. When I asked to speak with a supervisor, the representative came back off of hold to tell me that one wasn't available to speak with me, but one could call me in 24-48 hours. Obviously there was a supervisor there, and they just don't want to have a conversation about how bad their blender is at making smoothies. I highly doubt that they will even call me back - let alone try to resolve my problem in any way. Stay clear of this blender and company.
