This little box of bits Bosch has done its job. For the price, I am aware that these tools are rather intended for small DIY lovers like me, ie I do not think they would support an intensive and professional use. But in my case, the case fits perfectly in the screwdriver box is almost meets all my needs. I have not yet had to deplore the deterioration tip, although I realize that the "bright matting" of the material found on the end of the tips in contact with the screws, indicates a phenomenon that wear I will watch, but at 0.37 the tip, I think the box is a always a good quality / price ratio. I am satisfied.
