There are no silver bullet blenders, as of 2015, although the Magic NutriBullet Pro does come in a silver color. The Magic Bullet and silver NutriBullet both have an equal B rating from Good Housekeeping, with different pros and cons.
The NutriBullet and Magic Bullet both have B ratings, but they have each pros or cons, such as being dishwasher safe and leaving tomato sauce stains. While the original Magic Bullet is dishwasher safe, the NutriBullet is not. The NutriBullet is also not good for blending margaritas, although this ability was not mentioned one way or the other under the Magic Bullet's product review. Both blenders leave tomato sauce stains on the plastic jars, according to reviews. Both the NutriBullet and Magic Bullet blenders are quiet, have easy blade assembly and are good at grinding coffee beans. It is also easy to attach and twist the jars into place and operate the blender.
Both blenders come with a multitude of accessories, including several jars with handles, jar lids that screw into place and extra blades. While the accessories offer many grinding and chopping abilities, they also take up a lot of cupboard space. However, the single serving jars with handles makes it convenient to take a drink on the go.
