The box is installed stable and orderly. Thus, a long service should not pose any problems. Power 4 stars. The inner dimensions are unfortunately inappropriate. The box is inside too wide (4 mm) and long (3mm). Thus in the box the cards and my debit / CC cards rattle. That is not only annoying, but also not good for the card. I built a small wooden frame and use this as an inlay. Now everything is good. For the above problem, there are only 2 stars. I expect that the products are available on the German market are also available for this. Here I can not help that feeling that a possible "friendly" production for the entire globe was made.
