Oral-B iO 3 Duo Black & Blue Electric Toothbrushes
Verified purchase - review from a price comparison website
One step better toothbrush again. I have been using Oral-B toothbrushes for a long time (more than 15 years) and I think they are great. I even still have the original brushes, which are still functional.
These toothbrushes with magnetic heads are much quieter, which is a big plus over the older version. Already this one has several modes, so you can choose which one you want. It's nice that the modes are switched with a different control than the on/off button. I have that with my older one it's annoying even though it only has two modes.
It's more expensive overall, even the heads themselves are more expensive and due to the different technology they can't be interchanged. But it's not that much of a price differential.

I used to have an Oral-B iO6 toothbrush with a display, but that went away after 4 years. The rubber on the on/off button was worn out and I couldn't turn it on (apparently a defect in the rubber let water in). It looks like the Oral-B iO3 toothbrush might last longer due to the different treatment of the control panel. I've gotten used to the lack of a display, it's not a big problem for me.
simplicity
perfect price/performance ratio
quality workmanship
cleaning pressure sensor
three cleaning programmes or cleaning intensities
no display (unlike the higher iO brush series)
because of the lack of display you don't know what program (intensity) you have on, but I still clean on the strongest one
you don't know the current battery level due to the lack of a display
Cleans thoroughly, pressure sensor, led indication, high battery capacity
too big for my small teeth and mouth
