I dont think that one single classified sell is enough to bring the price to one key, Wait for more one key sales before making a price suggestion

1.5 comes out of nowhere.

Pretty sure it has 25 uses by default, that one only has 10 left.

Where does 1.5 come from anyways?

Must have the full 25 uses to be used for price suggestions.

you have almost no proof to back a 75% drop

you also have no proof for 1.5

Only full noise makers are priced - using a half full one like the one you've provided is invalid
