No flaws, no problems my screwdrivers, everything works as it is shown in various videos. One can safely exchange more than three batteries with this tool. Clearly, at the orders of magnitude of the tool to expect any special stability ,! But with the screws in the size of 0.5 to 1.4 mm length and a diameter of about 0.2 to 0.25 mm, no particularly high torque will probably be necessary. Incomprehensible are the reviews, Dei describe a rapid wear. One Fragr to what people have done with the tool ???
