Stripped screws are for people who buy $10 kits at the hardware store.
Why Not Just Buy the Cheap One?
Stanley and Hyper Tough bits cam out and round screws, and their handles don't allow proper torque. The Wera set uses a hexagon bolster to prevent rolling, a fine-tooth ratchet mechanism, and bits made from tough steel that stay sharp—it actually lets you turn fasteners without cursing.
The Buy-Once Math
A $10 screwdriver set is a consumable—you'll replace bits (or the whole thing) every few projects. The Wera set costs $60 but includes a lifetime warranty and the confidence that you won't strip a single screw. One tool that works forever vs. a drawer of garbage.
