Review on Professional 140-in-1 Precision Screwdriver Kit for Computer, Laptop, Cell Phone, iPhone, Tablet, MacBook, PC, Xbox Repair - Blue, includes 120 Magnetic Bits and 20 Repair Tools by Edward Henderson

Lots of bits at a low price. It has a set of high-security bits for those special fasteners that Apple and many others use to prevent consumers from repairing their products. For example, it has five-leaf and three-leaf bits. There are both standard and high security versions of Torx bits. Since high security bits also fit standard security clasps, I don't see why a set needs both. Perhaps this space would be better suited for adding another type of bits. However, hex bits are not a type of security. And it seems that the set only contains metric bits, no English bits. This is an obvious potential improvement. The bit holders are held in the case with Velcro fasteners. This allows you to move them. I moved them closer together so the bits fall out less.
