Since I use my Toshiba Satellite Z930-130 offered to buy additional memory, I needed a 7mm screwdriver TORX BO. Believe it or not, but the size of 7mm and TORX BO is almost impossible to get. The BO is important that a central hole in the screw - without which you do not get the screw.
With the turners of Wera, which are also processed very tidy the rest, but that was no problem. The heads are non-magnetic, which is not for me but bad.
