I was upgrading my computer with a mixed tool set that stripped after only a couple uses. This pressured me to buy a dedicated PH#00 screwdriver.
It does the job tremendously well. I finished the upgrade. A few days later, I had a liquid spill and had to quickly open the chassis to clean/dry out the inside of the body. The screwdriver worked like a charm in a bind.
Don't skimp on the important stuff. A cheap driver can ruin your screws and your computer. This driver does the trick.
