Well, the little aluminium casted part in the head of the toothbrush that normally breaks in two halfs at the thinnest wall parts, simply is constructed to thin. So it will break with verey toothbrush from these series when the brush falls on the ground. Just buy the spare head at amazon as mentioned by the Joe Fitness Academy and you’re done!

Ordered replacement part, came within 3 days at ebay. Didn’t have to replace the soft rubber inlet parts, only the connector.

Piece of cake, exchange of battery seems more labourous, but the brush still works for two weeks, so we postpone this job.

Very helpful instruction: the laptop only has one inconvenience that is mentioned: the tape that attaches the speaker wires onto the battery. A poor design.
