Having experienced many frustrations with other structures, for example with the principle of long screw that always leaves cork members in wine, I saw work with this corkscrew in a restaurant the waiter. After that I immediately ordered the Pulltaps and am absolutely thrilled. No excessive force, no cork in wine and ergonomically correct dimensions and quality design. Although there is a low risk of getting caught in the handling, but after you have understood the principle, there are no problems. A top product!
