My wife bought new toothbrush heads on her way home from work today.
They didn’t fit. She bought the “Oral B IO” heads, but we have a “regular” Oral B toothbrush, not the Shiny Fancy IO design.
And this is after she bought replacement heads last week at another store – which turned out to be “compatible for” a different brand :(
Ugh.
I “solved” this problem by losing my original OralB (non-IO) and being forced to replace it with an OralB IO, then finding my original OralB. I keep one in the upstairs bathroom and one in the downstairs, and now I can use either type, lol!
Oof, that could be a post entirely on its own!
