Toothbrush - battery operated (Goffs Oak EN7)

Hello all. I have a battery operated toothbrush to give away. It does work but can't turn it off unless I take the battery out. I used it for a few trips and it was great. No need to plug in. It still has a spare new head in the packet. If somebody wants to tinker around with it and fix the on-off button, it could be saved from landfill. Thanks for reading.
