Philips electric toothbrush for a new one is a refurbished machine?

No, all models of Philips toothbrush head HX3/6/8/9 are universally applicable. Feel free to change the model of the toothbrush head to use. Secondly, the genuine Philips brush head with the same model and the same batch of the same global origin is the same, only the packaging is different (the old packaging of the box affixed with the origin is actually the place of packaging, the new packaging has been labeled with the origin and packaging respectively), so the same date of the same model brush head is the same anywhere in the world to buy, the details of the brush head will not have any difference. Then, all kinds of brush heads are now at the end of the transition from old to new, and the old brush heads are fading out of the market. The new brush heads have been replaced with new packaging all over the world
