A:AnswerHello javi - Yes, multiple users can use the product. This model comes with 5 flossing tips and 2 brush heads. Please ensure each user has their own accessories.
A:AnswerI dont believe so. It plugs into 110 and European countries use a different plug and voltage. If you try to plug it in with an adapter it will go up in smoke. I do not know if they make one that is duel voltage. I believe you will have to get one for the European market or perhaps the cordless rechargable shower model and take it with you. Depending on how ling you are overseas you may no have to recharge it until you get back to the states
A:AnswerHello chip - An extra toothbrush is not available, but you can purchase additional brush heads. The toothbrush heads are color coated for multiple people to use the unit.
A:AnswerIf you didn't already find out, just pull firmly from the top at the brush head, that's how I got mine off. No button that I could see, unlike the water flosser.
