The Cuisinart SmartPower CPB-300 blending system includes one 32-ounce blend jar, an 8-ounce chopping cup and a set of four, 16-ounce travel mugs. It gets great reviews as a powerful, versatile machine that is popular for families who have multiple members because you can individualize smoothies by blending right in the travel cups. However, the fact that the travel-cup lids' drinking hole can't be sealed makes it unsuitable for some "travel" situations.
Small blender makes great smoothies and more. Most blenders give you a large pitcher or a single-serve cup -- but the Cuisinart SmartPower CPB-300 blender gives you both. You can choose to blend in one of four 16-ounce travel cups, a 32-ounce jar or an 8-ounce chopping bowl. Despite its small motor (350 watts, about half the power of most full-size blenders), owners say the Cuisinart performs well in a variety of tasks, particularly praising its ability to blend frozen fruit and larger chunks of fresh fruit for smoothies. It gets mixed reviews for its ability to crush ice; most say it does very well, but some say it struggles with that task.
Convenience mastered. One professional testing organization gives the Cuisinart SmartPower CPB-300 blender an Excellent rating for convenience (ease of use and cleaning), and owners agree. The blade assembly screws onto the top of the travel cup, and then off after it's blended. All parts are dishwasher safe, and with several cups included, there's less cleanup than with a standard blender, buyers say. Many commuters like that they can make four shakes before they have to run the dishwasher. If you're a two-smoothie household (or more), owners say the Cuisinart makes it easy to blend different shakes for everybody. The travel cups have lids, but with open holes at the top for drinking. Some owners wish the lids sealed shut, but others point out that the design is perfect for a straw.
Mixed reviews for durability. We found more durability complaints about the Cuisinart SmartPower CPB-300 than we did about some other blenders in this report, but the number seems comparable to other blenders in its class. The main complaint seems to be that the motor burns out after what users feel is not particularly heavy use, or that they smell "burning motor" smell on more challenging jobs. However, over the thousands of reviews we evaluated, these complaints are in the minority. The majority agree that the Cuisinart CPB-300 is a durable, powerful appliance. The blending containers are made from the same super-tough BPA-free material (Eastman Tritan co-polyester) as containers on blenders costing two or three times as much. The CPB-300 comes with a three-year warranty.
Editors of ConsumerReports.org test and rate more than 75 blenders, including the Cuisinart SmartPower CPB-300, however, they include it in the full-size blender category, rather than individual blender category. It's tested for its performance in blending yogurt, pureeing soups and crushing ice for smoothies; as well as convenience, noise and durability.

The Cuisinart CPB-300 is among five single-serve blenders Valentina Palladino reviews for Wired. She notes that it's powerful, but a bit loud and takes some practice to get the right consistency in drinks. She likes the size option of the included cups/accessories, but the fact that the travel lids don't close is inconvenient.
