Bests & Worsts Reviews from Amazon

First off, let me begin by saying that this unit can make a real smooth smoothie and I really wanted to own one of these! So much so that I tried 2 of them thinking that the first one may have just been a dud. Unfortunately, after trying 2 of these, both had issues with the blades either pitting or bending or both. The issue with the blades on the first one was not noticed until after about 3 month of use while cleaning it as I wasn't looking or expecting to have an issue with the blades. On the second Ninja, being aware of this issue, I decided to inspect the blades after each drink. Within 3 days of owning the second one, the upper blades began to show some kind of pitting. The real surprise was that after using just bananas, apple, kiwi and soy milk and omitting the frozen blueberries that I use to include in the first Ninja, the second Ninja began to have blade issues as well. No ice was ever used in either of the units (even though these models are capable of processing ice). Both units were used as per instructions, cutting the fruit into smaller pieces, adding adequate amount of liquid, not over-filling etc. To my disappointment, I couldn't justify owning one of these, being that I would have to continually inspect the blades and would be worried about the possibility of ingesting fragments of blades. With that in mind, I decided to return the second Ninja for a refund. I would not consider purchasing another Ninja unless some substantial quality improvement is made to the blades (see photos of blades included with this review). In contrast, I own a mid price regular blender, and after a period of over a year, no such issues with blades. The blades are perfect! No bending, no pitting, no sign of wear whatsoever! I'll be going back to using that even though the Ninja does make a smoother drink. I would say in closing that if you own a Nutri Ninja, check your blades!
