wow, they do a lot of things don't they?
It seems like they don't need attaching to a phone for me.
I have had an Oral B type 3756 for (I can't remember how many) years.
It had a thingy dislplay as well. That just sat in the cupboard.
I do rather like the 30 second buzz thing.
However, it wouldn't be hard to have a timer on the shelf.
I don't know if I benefit from the red flashing thing when I press too hard.
I do think I back off a bit.
Not sure that I would pay extra for those gizmos.
Once you have a motor that jiggles the head, the rest is all a bit of just gizmos it seems.
I replaced the battery in it again a couple of years ago for a better and bigger capacity one.
It was better than when new.
I will look more into the battery type next time.
@slapo did you try different types of brush heads?
I had one that shook the teeth out of my head. Another that felt huge.
I prefer the simple, small ones.
It definitely does a better job than manual brushing for me.
