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.
This is def the case for me. I used to bring the old fashioned toothbrushes for camping (well, for any travel). I noticed a HUGE difference when I’d get home again.
Now I just bring the normal toothbrush. The battery lasts long enough for most trips that it’s fine.
