Kitchen Mama Auto 2.0 Blue
Score: 72/100Rankings

The Hamilton Beach Smooth Edge electric can opener uses a side-cutting blade to produce smooth, reusable lids and handles tall cans up to 6 inches. Its short power cord and reported durability issues may limit long-term use. Ideal for home cooks seeking safe, one-hand operation.

The Kitchen Mama Auto 2.0 is a battery-operated, handheld opener that cuts 360° smooth edges and includes a built-in magnet lid remover. Its reliance on non-included AA batteries and occasional magnet issues are drawbacks. It fits users needing portable, hands-free operation for standard cans.

Professional reviewers commend the Hamilton Beach Smooth Touch for its side-cutting safety, ergonomic lever, and mess-free operation, positioning it as a convenient kitchen essential for busy households. However, they caution that the short cord and reported short-term durability make it less suitable for heavy or commercial use, and they note that not all models include an automatic shutoff.
Everyday users love the ease of one-handed operation, the smooth, non-sharp lids, and the ability to open tall cans, often describing the device as a noticeable upgrade over handheld openers. Recurring complaints focus on the short power cord, occasional mechanical failures after a month of use, and occasional metal shavings, leading some to question long-term reliability.

Professional reviewers commend the Kitchen Mama Auto 2.0 for its innovative tilted blade that delivers smooth, non-sharp edges and its convenient one-button, hands-free operation. They also note the added value of the built-in lid remover, but caution that the magnet can be unreliable and that the lack of included batteries detracts from the overall experience.
Everyday users generally love the effortless button press and the safety of smooth, resealable lids, especially appreciating its compactness for travel and small kitchens. However, recurring complaints focus on the magnet's occasional failure to lift lids and the device's limited performance with non-standard cans, reflected in a low ease-of-use rating on Target.
