Xiaomi Mi Precision Screwdriver Set

The Xiaomi Mijia precision screwdriver set features 24 S2 steel bits co-developed with German tool brand Wiha.

It depends on the device. Phones and laptops are generally safe if you disconnect the battery first. Power electronics (chargers, power supplies) can retain dangerous voltage in capacitors — always discharge them before touching anything inside. Wear safety glasses when prying open enclosures.
