Well this refill is a Wallflowers warming unit from Bath and Body Works store, and the warmer does plug into an outlet in the wall - it does not work with Glade or Airwick as far as I know, is that what you mean?
you know I have never tried to fit these in the other brands, I may go home and try it out now! They just look like a different shape so I figured they don't work...I will report back :)
