This little set of screwdrivers is great to have around for those tricky little screws that most people won't have a small enough tool for. The screwdrivers are made of a good quality metal and aren't stripped by screws as some cheaper screwdrivers are. They're great for small screws such as sunglasses arms and electronics. The attachment swap mechanism is a little stiff and its difficult sometimes to remove the attachment. The screwdrivers come in a solid little case so you can put them anywhere you might need without worrying about losing any pieces.
