Design & Everyday Usability
CROWNFUL: Designed for Aesthetic Setups
CROWNFUL clearly targets users who care about visual simplicity and clean setups. It blends perfectly into:

The glossy finish and compact form factor make it especially popular among skincare users.

Understanding Thermoelectric Cooling
Both models use thermoelectric technology, meaning:

They typically cool to 32–40°F below ambient temperature, not a fixed fridge temperature.
