Review on 140-in-1 Professional Computer Repair Kit: Precision Electronic Screwdriver Set with 120 Magnetic 🔧 Bits - Ideal for Computer, PC, Macbook, Laptop, iPhone, PS4, and Small Technical Tool Repairs by Francisco Holmes

You really get a lot of different styles for this price. There are some head designs here that I have never seen on a mobile phone or in a PC. Also, as far as I can tell, this set has every type of screw head I've seen. The adapter and all the inner ends of each connector are also magnetized, which is really great when you need to remove a tiny screw in a tiny spot and can't afford to lose the tip. The flex bar also seems to work as intended, but being so short it might not be of much use except in very specific circumstances. You'll also need to grab the plastic part on the outside of the shaft to keep the drive spinning, so you'll lose even more space if you need to fit everything you can into your project's case. Other than that, it's a pretty basic case with higher quality parts than you'd expect here, plus a fair amount of bits and adapters.
