Precision Screwdriver Set from Kaisi Review

When I first started working with electronics the only screwdrivers I had in my possession were big and bulky – the kind I used for household repairs. It soon became evident that smaller, more precise tools were required for electronic building and repair. And the most economical way to get started was to buy a precision screwdriver set.

For instance, this Kaisi precision screwdriver set has everything I need for most of my electronic repair work. The kit contains 111 screwdriver bits and a 1/4 inch screwdriver adapter. I’m a big believer in using tools as they are designed, and electronics screwdrivers should never be used to pry something open. That’s why it’s so great this kit includes tools built for the purpose of prying. It also includes tweezers.
