Video at Amazon.com See anticipation: The castle is very solid and provides at least the same protection as a normal lock. The opening without a key is very fast and is very convenient. You still need both hands and not only just one in order to catch up. But there is a major shortcoming, namely the manual. She may be illustrated, but the images can be a little to see if, for example, the castle is now open in the picture or not. In addition to the images, there is a bit of text with numerous translations in an estimated nearly 20 languages that will help a little more. Still, I had still not come out how I can get open from the box after an hour of this castle. While there is a video tutorial, but can be seen at the link specified in the manual is not immediately and you have to really look at the manufacturer's website afterwards. If you have this video then found eventually, they do not help me at least, still further, because both imaging and text instructions and video all information withheld simply: Each lock has its own individual start code can only be found in the manual top right is what was in my case, the lower left bottom left (in the video I zoom it in the beginning to). These arrows are not shown as startup code and impatient people they could simply ignore. Without this information, the castle is not as expected and according to Internet are very many face this problem. One is even inclined to re-apply using the reset lever on the back of its own code, which could under certain circumstances, however, damage the small reset lever, which consists only of plastic.
