What’s the purpose of this item?

Do I really need for an item which serves that purpose? How would it benefit me?

Do I already own something that can be repurposed/fixed/made to serve the same purpose?

Can I borrow such thing from a friend who does not need it?

Who is selling this item and do I want to endorse them by buying it from them?

In what ways does the item make me dependent in therms of fixes, supplies, energy consumed etc. On whom?

Do I really need that item right now, or can I can buy it later so I have more time to consider the above?
