Powerful dental and gum irrigator device

Oral-B device for protecting teeth and gums. The device was purchased from Extra, used only once to test it after opening; it comes in its original box and has two modes: strong and gentle. The reason for selling is that I expected it to spray air, but it only sprays water, so I didn't get a chance to return it. Its original value is 285 as shown in the purchase invoice.
