In order to determine what model your Ninja Blender is, look at the small information section at the bottom of the base of the blender. Look for the word "Model" which will be followed by the model number, which is hopefully "NJ600".
The NJ600 Professional Blender is only available in one distinct color scheme: black plastic body with a silver panel. Each button, excluding the "PULSE" button, has an LED light underneath it that lights up when the button is activated. The "Power" button will light up when the device is turned on. The NJ600 also features a three level blade column (two blades on either side of the column at each level).
