Canslab Ultrablade PRO Auto Stop
Score: 80/100Rankings
The Canslab Ultrablade PRO is a rechargeable, hands-free can opener that delivers fast, quiet side-cutting with an auto-stop feature. Its trade-off is incompatibility with rimless cans and vague dimension details. Best suited for arthritis-friendly home use and camping.
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.

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.
