Which is a positive phrase in the sales industry ? 1- Saying that a product is used, or 2- Saying that a product is pre-owned?

Pre-owned is consumer healthy.

I see that used products indicate their continuous value of the product to its users. pre-ownership does't pass the same message. I think that this is true especially in the field of computer programs. Being used is more important than saying that customers urchased licences.

Saying 'that a product is pre-owned' sounds better.
