Good device in an appealing presentation. Even more upsetting that the device is already switched on at the slightest pressure, also the torch for example. What good is it to me if I rumschleppe a spare battery with me, the lights go unnoticed all the time in my pocket and then has correspondingly less capacity when I need him. This happens quite often, because really sufficient only slight pressure (in the case) and it turns on. Then again and the thing lit until you realize it. That was definitely not meant to last, because this would be a key lock as the mobile phone etc. useful. Real stupid!
