I have lost the key of my cashbox and briefcase and no longer found, so I've tried these things with this Dietrich set aufzubekommen and behold: With a little practice and the right Dietrich can reach his goal and I even have the cassette and the trunk to get back! So if you have lost a key time, this starter kit is the perfect solution and the price is also reasonable for these purposes, you do not need so spend triple the price. Of course, the Dietrichs are here something like "Stan Zware", yet they are also not sensitive or tend not to break. Recommended!
