I repair smart devices for a nationwide company and when I started I had a reliable 3 piece repair kit. After getting to know the drivers from Wiha, I decided to try them out. My co-workers are jealous of these screwdrivers, not only for their clean, unified look, but also for the secure grip of the bits on different types of screws. Usually people ask me to use my tools, not the company's battered tools, because they know they will get the job done. The tweezers are also amazing because they have a tip at the end that's small enough to be "sharp" but flat enough to wedge under the coaxial connection of various Samsung devices for easy access with a simple twist of the handle. I love this SET! Buy them and love them too!
