I had this toothbrush for a while, and when I ran out of heads and wanted to buy some more - the only shop that had them in Stockholm in Sweden informed me that Braun (Oral-B) does not supply them anymore, and to request it from 3rd party would cost me around 15 pounds per head. Wanted to say goodbye to my Supersonic brush, but then decided to look on Amazon. Bingo! My toothbrush will serve me some more time. Went for the original option, as read some negative reviews on the quality of non-original heads.
