The Rosenstein & Söhne - Electrical Can Opener is a fun kitchen accessory and does its job well, but is somewhat impractical due to its shape. The edge is cut open neatly and is quickly ready for use without further preparation.


  • Lies well in the hand
  • Appealing design


  • Impractical to put down as the back is arched
  • Foot in fin optics does not allow any stand
Even if putting the device down requires optimization, this can opener scores with its design and ease of operation.


The can opener from Rosenstein und Söhne is packed in a plain white cardboard box and is equipped with a somewhat confusing operating manual. Batteries were not supplied, which makes immediate use impossible. The battery compartment was easy to open, but the description was not very clear.


The can opener light blue and white designed and reminds of a dolphin because of its shape.

Execution and test result

To open the can, place the opener on the can so that the blade touches the edge of the can. As soon as you press the button, the opener starts to turn on its own around the can and open it. There is no automatic switch-off and you have to watch yourself when the can is open. A quick switch-off is possible by pressing the button again.

If you remove the opener from the can, the lid of the can is held to the opener by a magnet. Due to the shape of the opener, the opener lies well in the hand, but you can only put it away impractically because it simply tips over or rolls to the side.

The can is cut open cleanly and the edges are without burr. You can easily put the lid back on the can to store the contents and close it.
