Bought these toothbrushes for our holiday, as we have a family of 5 and the originals are so expensive. We started using them and they were ok. They did feel a bit different. but as they weren't originals we just let it go. Then after a week, each head stopped turning. They were still vibrating but there is no turning to the head. We have since bought the originals again and they are far better. To sum up, these ones do clean but they are nowhere as good as the originals. Our mouths feel much cleaner using Oral-B's.
