Cons:
- As indicated in the title, this brush heads develop after some time an almost unbearable noise, I'm so not used by the very pleasant and silent running Standard brush heads. I chose because of the actually lower volume in the cleaning process for a sonic toothbrush and against conventional electric toothbrushes and unfortunately had to find that the brush heads rated higher volume produced than conventional electric toothbrushes. Immediately after the purchase of the electric toothbrush I used the standard brush heads and thus comparison values which I can use for this review. The Diamond Clean brush heads, I just wanted to try it as an alternative to the standard brush heads, which actually every 4 existing in the pack brush heads after some time were very loud. At the toothbrush itself it is not the way, because when you switch to a standard brush head while brushing the volume is again pleasantly quiet.
- Compared to the standard brush heads to use them much more quickly from what is revealed on the one hand by the color indicator of blue bristles and on the other by the deformation of the bristles in general.
Conclusion:
In future, I will revert to the standard brush heads. These last longer, are less noisy (as you should expect from a sonic toothbrush) and, moreover, even for less. The second star is justified only in the good cleaning result.
