not everyone will be enthusiastic as the previous speakers

Vorneweg the cartridge system is quite something nice and comfortable, also with good cleaning performance.
Handling is also very easy. The only thing is something ne fumbling, is down close to closure. This force is properly needed and when the cartridge case is not pressed firmly on NEN table or the like, then sloshes of the precious liquid equal something over.

As I said, the cleaning performance to be proud of. The whole under the faucet or only with ner brush does not even come close to a similarly good result.
This is a painful usually clear on vacation if you have to give it up.

So why only 3 stars?
Therefore one must make clear that datt thingy after approximately 4 weeks is flat. Approximately a week before you notice a strong decrease in the quality of cleaning. On the one hand residues in the base station and also the fact that the contamination indicator quickly goes down the razor.
If you still reread where the cartridges are produced (China) and also reread what is in there, then one suspects the profit margin.

The thing that bothers me is zwote that a large part of the cartridge is alcohol. This known to be dissipated by the opening.
Now when I go out times of an average use of the cartridge 5 minutes during the day, and I now generously aufrunde to half an hour -
then the part of the day over 23 hours pointless open for as little time and empties so hour after hour. Without the customer has what it.

One can keep the shutter, and close the cartridge always after use. This is again just ne Fieselei as a later re-opening.
Because I wish of a group as a brown solution to what can be come here for the customer.
Not for nothing can be nobody home a bottle of good whiskey or grappa after einschenken rumstehn open.

Conclusion: Simple, convenient and good cleaning performance. But here an idea must be found, as the cartridge reseals after use, at least not as wide open as now.
