The Vermutstropfen: Battery replacement in separate numeric keypad is a disgrace. The CR2430 - Battery can only be reached with a screwdriver and the old battery can be removed only with skill and tweezers. When inserting the new battery, the spring must be pushed very far up, so I assume that the spring is soon worn out and no later than after the third battery change the battery will no longer hold in the tray. The battery change was necessary after 6 months of virtually daily use; okay. But getting on and screwing of Batterieabdeckdeckels is a clunky affair. With certainty the extremely short screw (about 2 mm) will soon no longer get stuck in the thread and it will then have to be converted to a Tesa strips. As has triumphed over the Technikder obviously the designers.
