What every best has:
User reviews are plentiful and mixed. While many consumers are enthusiastic about their Magic Bullets, we also read many complaints about fragile plastic parts that break and an inflexible policy that forces customers to pay for a new base instead of a single replacement part. Many also say that contrary to the as-seen-on-TV infomercial, the Magic Bullet blender doesn't do a great job when chopping certain vegetables such as onions, garlic and tomatoes, delivering an unappetizing mush. Reviewers at InfoNOTmercial.com state that one reason results look easier and nicer in the commercial is that small cherry tomatoes and pearl onions are used in the demonstration -- something that's not revealed to the viewer. The fact that the blender could overheat if operated for more than a minute at a time also gives users and experts pause.
In the end, reports largely agree that the Magic Bullet can be useful for certain tasks If you don't expect too much.
