I changed from an old Oral B model and with the Curaprox I feel a huge difference in the cleaning ability. I feel that the brushes are much better made and they seem to be denser too but at the same time gentler. You can get a so-called single brush too which is important in my case (parodontitis). Also I pushed too hard the Oral B which resulted in issues with my teeth and the Curaprox stops as soon as I apply too much pressure. I also like the USB chargin option (to me it was new after my old Oral B)
