Purchased from Rakuten 4 months ago and used for about a week. Regarding the filter: Please purchase a new one when using. It's clean with no noticeable stains or scratches, but please understand that it is used. The charger/adapter was bitten in an instant, so this is an offering of the main unit only. The type in the second photo I had at home worked immediately (operation confirmed/this is not included). No price reduction.
