Broke in two days
I bought two packs of these brushes for my personal use. These are first of all not Oral B brand but Oral B compatible. In reality, this is not at all Oral B compatible. The head does not fit the Oral B handle well. It is always loose. Also, the head started to shake abruptly after two uses. It makes a grinding noise. I would not recommend buying this product at all. The return policy doesn't allow me to return an open pack, so, keep that in mind when buying.
