Expensive bad design! The early effect for your pocket is not described as the key bits out are always at least one side. Worse are the insufficient lockable screws! One has dissolved after only one day and I had the key in his pocket and a salad even temporarily lost and consuming search must !!! Another negative factor is the lack of sense of the castle, as it exerts a powerful lever in the hands with the fixed keys and has absolutely no feeling for Schlossgängigkeit! Cancel will soon take the consequence and not always is a lot of space between the lock and frame, so that the opening process looks rather awkward and much longer than usual, is also can be the key distinguish unintuitive more in most cases. Detrimental even in the dark, as it has the characteristics of the key bits is no longer in the hand and can palpate! For me, for many reasons a very expensive bad buy!
