The nutribullet Pro+ is good for single-serve smoothies. With both its 32-ounce and 24-ounce jars, it makes a very smooth blend with stubborn ingredients like leafy greens. It's an easy process, although some blenders can make smoothies faster. A matching to-go lid is included for each jar, so you can easily bring your drink with you on the go. Unfortunately, while the jars and lids are dishwasher-safe, the blades are not.
