Overall, the product does indeed a stable impression, but the built-in lock cylinder is lowest cheap goods. There is a disk lock with 6 leaflets that no protection offers before picking. Even without tools I could with 2 hairpins in less than 5 minutes to open this lock-destructive, with a corresponding pick it goes even faster.
For a reasonably skilled thief is this castle therefore no obstacle, then prefer to invest a few euros more.
