Floor model, often

DEMO

Think of what stores might call a trial version of a product that customers can test before buying. It’s short for a common marketing term.

"Floor model, often" hints at something displayed in a store for customers to try before buying. The word "floor" suggests it’s a physical example, while "model" implies a demonstration version. In retail, these are commonly called "demos," short for "demonstrations," making "DEMO" the straightforward answer.
