do not buy
They stop rotating way before it's time to replace them with a new one. One stopped rotating few days after I started using it. I will only buy Oral B genuine from now on. Also, it seems the bristles are not the same quality- the teeth do not feel as clean. With Oral B brushes, when you replace a fresh one, after first brushing, the teeth feel like you just had your teeth polished at dentist's. Not with these. These seem to clean at the same level as the worn-out Oral-B brushes.
