Packaging: Always 4 heads in a pack. Although is suboptimal but acceptable. Annoying were the slight plastic odor of the packaging and the instructions for use with references to the wear indicators which are in black and white. Irritating also the bit to imprint in German on the front, the rest is in English. On the positive side that can be opened without the packaging tool.
The heads: I can make no plastic smell, visually it resembles very much the Oral B heads. Disadvantage is that the colored rings are fixed at the bottom and thus can not be exchanged, for example, suitable for family members (also works with the originals rather so-so). The rings are always money, green, blue, red inside the packs.
Since I only have an older used head because I do not know whether this flat rate heads go smoother, as compared to my head used they do.
For cleaning: The bristles feel much harder than that of Orginals. I'm going hard away from the thus a decent clean between the teeth would be possible only if one presses heavily, which in turn would be bad for the gums.
Conclusion: No lohende savings compared to the additional price of Orginals. If that would save the advertising could also offer the same price with the same profit margin that certainly. The remaining heads I will not use.
Do not buy!
