Review on 🔧 6-Piece Magnetic Screwdriver Set with Non-Skid Handles in Various Sizes and Colors - Professional Repair Tool Kit for Electronics, iPhone, PC, Jewelry, Watch, and Eyeglass by Tim Purdie

I needed magnetic screwdrivers to drive difficult screws into a fragile machine. This set is a FAIL. Their magnetism at the end of the screwdriver is so bad that it can't hold a tiny M4 x 8mm screw and keep throwing it at the car. A 4mm washer for the screw will hold up fairly well. I've tried a screwdriver on M3 screws and it's best at dropping the screw about half the time. M5 - forget it, I don't even take it. Nice to look at, pleasant to the touch, but basically a useless magnetic tool. I tried to increase the magnetism with a large strong magnet - after two days of "loading" there was no difference. The only test left is to try heating the tools and then try applying a strong magnetic force to see if it holds.
