Break after a couple weeks use.,
Verified Purchase(What is this?)
I was so pleased to have found this product. Originally I had purchased a supermarket's own brand compatible oral B brush, but they were a slightly different shape and felt weird in the mouth - so when these arrived, and they felt just like the branded ones, I thought to myself I would never buy the expensive branded ones again!
Then a few weeks later, I noticed the mechanism inside the brush wasn't working properly. It buzzes a little and shakes when cleaning your teeth, but when you apply pressure during brushing, it's no longer doing it's thing! When comparing these brushes to the branded ones, you can see when you shake them a little side by side, that the unbranded ones are really loose and the branded ones aren't, which gives a different clean.
Back to the expensive ones. You do get what you pay for!
