Specifying a hair dryer that people keep using
Weight balance, noise and cord exit decide repeat use far more than wattage does.
Dryers are judged in the hand within a few seconds. A tool that is nose-heavy tires the wrist on long hair, and the user's conclusion is that the dryer is tiring rather than that its balance is wrong.
Noise is the second factor, and it is a motor and airflow-path decision rather than a specification line. A quieter dryer at the same airflow is experienced as a better dryer even by users who could not say why.
Cord exit position affects how the tool hangs and how the cord fatigues. A cord leaving the handle at the wrong angle is pulled across its own strain relief every time the dryer is set down, which is where cords eventually fail.
Wattage is the number printed on the box and the weakest predictor of whether the product is liked.

Why heat-up time and recovery decide a styling tool
Users do not measure plate temperature, they count passes, and pass count is set by recovery rather than by peak temperature.
What reliability testing before tooling actually catches
The faults worth catching are thermal and mechanical, and both are cheap to fix in a prototype and expensive to fix in steel.
How ODM development differs from catalogue sourcing
Catalogue sourcing buys a product that already exists; ODM buys a product designed against your market and price point.
