Quick and clean shave

As my Vorrezensent also I was 7 test the Braun shaver Series (765 cc) as part of a Trnd project.
The Model 765-cc is a pure dry shaver.
The following is important to me at a dry razor: it should be as time efficient and yet thoroughly and smooth shave. And there should be no redness. I use for over 30 years only Braun dry shaver and think I have a good comparison opportunity here.

So far, the model has met all my expectations: by a much faster oscillating head (Turbo Mode) I need actually about half the time that I have been with my current needs Braun Series 3 dry shaver.
The shaving is efficient and thorough. I need to shave only about 3 times more than a somewhat inaccessible location (eg in the chin flexor), to get a very close shave. This result I had never able to achieve with a dry shaver.
Redness are not yet occurred, which may be due to the 3-fold flexible heavy head with Senso-Flex.

For this reason, the Braun Series 7 Shaver has been fully proven.

There are other details that I would like to mention: the shaver is solidly built and feels good in the hand. One has the option to adjust the sensitivity of shaving (whether intense or less intense) - this is indicated by different colors of LED function lamp.
The battery is been consistently strong and does not let up even after about 30-40 minutes. The charge capacity or the remaining term can be read at the end by a small ad.
The shaver comes with a charging and cleaning station. This looks great, but also needs some space.
The contamination level is displayed on the loading and Reinigungsstaion. One then has the opportunity to make a quick cleaning or deep cleaning. For this one needs a cleaning cartridge which is employed in the station. A cartridge should last for about 30 cleanings.
By cleaning the shaver is actually freed from all residue stubble. Both in Fast mode and intensive mode.

But with all positive criteria I have something to complain about:

- By the Turbo mode emmittiert the razor a very high-pitched tone. Mich had spontaneously remembered it the first time on a visit to the dentist. This is something ugly, but you get used to it.
- Which makes me rather skeptical, is the cleaning cartridge. Even if this should be enough for 30 cleanings and you do not perform a quick cleaning after each shave, so you have to buy more cartridge sometime. This attracts ongoing follow-up costs. The prices are different, and there is also value packs. But it is still roughly an average of 5, - per cartridge.
Here it is worth considering whether one does not offer a large refill to the spent cartridge easy refill can.

For these two reasons I deducted a star.
Otherwise, there is so far a technically super sophisticated model. I had never had a better and more thorough dry shaving.
