Energy can base versus sleeve or clamp
Choose the feature you actually need.

A wider resting footprint
Steadi widens the support beneath a compatible container. The complete holder needs 5.2 inches of supported space.
Temperature and closure
An insulating sleeve or resealable container addresses different concerns. Steadi has no insulation or leakproof claim.
An attached holder
A desk attachment needs a compatible edge and clearance. A freestanding Steadi does not attach to the desk.
