I have two type of Philips Sonic Care electric toothbrushes, one with three (3) settings, SuperClean, Clean, Sensitive Gum; ie, different vibration intensity, with SuperClean the most powerful and Sensitive Gum the least powerful. The second type of Philips Sonic Care electric toothbrush I have is with two (2) settings, ie Clean and SensitiveGum, with Clean the more powerful and Sensitive Gum the lesser powerful. I am very pleased that Brushmo replacement heads work seamlessly with Philips original electric toothbrush and the SOFT bristle heads work perfectly than the original Philips brand.
