The smallest Torx screwdriver was broken after just 8x screwed, as apparently are the tiny case screws of the laptop of a harder material. And at very low application of power, since I did not want to damage the screws!
Price, supply and delivery are top, but that is all of no, because now I'm standing there with a laptop in which all screws are loose, and have to buy another set to get him back right screw up.
