I bought this box because the content was exactly what I was looking for. The good reviews have helped. Unfortunately, I can this box, as I received it a friend, not at all. The box itself is stable and can be closed well. The arrangement of the parts is achieved. Unfortunately, all the bits are not round. I tried all Langbits and the quality of axial accuracy is so bad that I succeeded with difficulty to sink screws in wood. The eggs at the top was so pronounced that it ever could achieve something only by compensating movements in the slope joint with the screwdriver. I have tried different screwdrivers, working absolutely reliably and quietly with other bits. This effect occurs even when the quick-change mounts with short bits. So that was nothing. Go back.
