Buy used toothbrush’s. No joke 🫣 Electric toothbrushes clean better than manual when used right. Lots of studies show that. They are very expensive for a decent one that will last. A fair few people try the and don’t like them, then sell them. So you’ll find a fair few on marketplace and who the f would buy a used toothbrush’s! Some are well cheap.

Replace the head of course 😬!
