Are too soft

The ProResults I wanted to try it because they have a larger head than my previous brushes. This is true and what is very pleasing to the additional rounds on the gums, where compliance with the teeth to be too soft. I have a feeling that the cleaning performance significantly lower. Next time I'll try the hard DiamondClean heads.

Otherwise, everything is according to Philips standard: The bristle indicators indicate when to change the head, and a set of colored rings to mark their own brush is attending.

(Without star reference: I second the criticism of packaging to weld four heads so is not only pure waste production, but also quite annoying this type of packaging is one of the range cast!..)
