- Shorter service life (max. 4 weeks) as ProResults (6-8 weeks).
- Cleaning action in the interdental spaces is less than with ProResults.
- The molars are more difficult reach.
- The bristles are rel. hard.
- Slightly higher price than ProResults.
- Louder noise when brushing your teeth with this brush head than ProResults.
Basically, I am not, nor my wife of this new, highly acclaimed Diamond Clean brush head
convinced. We use the remaining DiamondClean heads and then buy back the standard ProResults brush heads.
A note at the end: Whether the teeth have become white, or not I can not judge. The subjective impression is certainly unchanged.
