YES, that is correct as tenkan explained. The word “DEMO” in all caps is a label that Phonak puts on their demonstration/trial models for borrowing and trying out ONLY.
That is not to say they are at all different from the model YOU will buy, but demos are in limited supply, so audis need to have one labeled DEMO so it won’t be sold by mistake.
Similarly, I am “borrowing” a pair of Phonak Lumity Life aids (as my other pair was sent in to Phonak for repair). These aids are clearly stamped: PHONAK - TRIAL on the case so they won’t be sold by mistake. Hope that puts your mind at rest. You WILL buy the identical device, and it will be BRAND NEW, never used or tried out by anyone before. And that’s a good thing, cuz other users could damage a unit and then just turn it in after trial.
