These heads are great. They give a thorough cleaning without being too hard. I recently ran out of heads and went back to my manual soft toothbrush. 1 day later I had to go get more heads for my electric toothbrush, as my teeth felt so furry after manual brushing, even with lots of good old fashioned elbow grease!

I hated my electric toothbrush until I changed to these softer heads.

If you gave this electric toothbrush, replacement heads are a must. I find these to be long lasting and I like the smaller head, making it easier to use.
