I have applied the production after all. My shaver is a Braun 760cc.
The cleaning of the Brown cartridge causes a little effort and is not quite as simple as can be seen in the video of the manufacturer. But it is doable. To completely remove stubble and greasy deposits, you should work with warm water and some admit household all-purpose cleaner.
For hygiene reasons, and I would completely clean the cartridge with each refill.
I emptied my last original Braun cartridge after 30 days, although still enough liquid was contained. The reason was that after this period, an unpleasantly musty sebum smell has formed, which was also reflected on the shaving head.
After ordinary cleaning and refilling with the product offered here I'm happy again.
The cleaning is evidently just as thoroughly as the original, the fragrance rather better. By no means be described as pungent from others, but rather easily as a detergent. The fragrance is very weak (less than the pseudo-lemon smell from the original) and therefore negligible in any case. I suspect that other reviews relate this point to an old recipe.
Up Thumbs: From my perspective!
About long-term experiences I'll report back when the time comes.
