I'm excited! At first glance the opener as the One-Touch works, but he has decisive advantages: The Kuhn Rikon 2240 are manual, so I can easily regulate the contact pressure itself. After my 2nd One-Touch now I know how important that is. He also does not cut under the rim, but obliquely from above. So I can actually replace the cover. Because I'm over 70, I have a long experience with the most diverse openers, this is so far simply the best! The only negative is the much too small Instructions, which also shows no clear images. With the can not really start something you! My advice: start on the top edge at a right angle, the impeller clockwise until it sums up, and then gently push the handle down and continue to turn.
