Test: We tested the technologies in the Braun Series 7 electric shaver – Communication – Science and technology

Although razors are not a typical representative of technological gadgets, they belong to one of the categories of consumer electronics. We therefore decided to try an electric shaver from one of the highest Braun series, the Series 7 model.

Electric shaving has as many supporters as it is opponents. While those in one camp appreciate the simplicity and virtually maintenance-free operation, others lack the feeling of clean-shaven skin and less irritation. The truth is that razors have probably undergone greater intergenerational development than any other consumer electronics. They no longer pull the beard, there is no need to go through it one place ten times and risk skin irritation or imperfect shaving in less accessible parts of the face.

On the other hand, manufacturers are duly paid for their efforts and technological sophistication. Of course, electric machines are also available on the market for 30 or 40 euros, but many of them have a limited life without the possibility of extending it by replacing the head with the British. In addition, they may not shave perfectly, consistently, or the speed at which the razors rotate is too slow for the shave to be painless and without consequences. From our own experience, we can confirm that the moment we reached for a cheap electric razor, we returned to wet shaving with razor razors in a short time. In this case, the price of the spare head is in euros.

Planchet or milling machine? It also depends on the skin type

Electric razors use either vibrating plates or rotating cutters. The former have a rectangular head, which in some cases can be fully flexible in order to adapt to the contours of the face. The rotating turn blades are located in circular surfaces that can rotate flexibly. From our own experience, the milling machines suited us less, as the rotating blades had a more aggressive effect on sensitive skin than the planchets. The tested Braun Series 7 model has plates on an articulated flexible arm. The movement has AutoSense technology, which adjusts the performance of the motorcycle to the thickness of the mustache. For example, above the upper lip and on the cheeks, it was noticeable that the planchets oscillate faster than, for example, on the chin with a finer stubble.

The specificity of this type of razor is that they are rather “maintenance”, which in practice means that they are not suitable for shaving a longer stubble. They can’t handle it so well and shaving is long and unpleasant in places due to the length of the hair. From practice, the shortening of a four to five-day stubble proved to be the best for us, but it is very individual. After more than a week of not shaving, the machine no longer served so well. Also, due to sensitive skin, shaving the next day did not work for us, but not until the next day at the earliest.

Instead of shaving, also trimming or shortening the hair

A pair of buttons is used for relatively intuitive operation. The main button turns on the machine, holding it down again locks it before accidental start-up. The second button is used to activate the display or inform about the remaining life of the plate. Replacing the blade with a trimmer is very simple and literally two “clicks”. The trimming attachment can be used, for example, when shaping the chin or shortening the hair in the armpit or on the body (except for intimate areas).

Braun offers two to three variants of otherwise identical machines in practically all higher series. In the case of the Series 7, there is only a choice of machines with a travel case and a model with a cleaning and charging station, in which, however, it is necessary to change the cartridge regularly. The model we tested is only supplied with a travel case, but the charging station can be purchased in addition for about 60 euros. In addition to the case, the package also includes a charger and a cleaning brush. You will need to use the charger about 1 to 2 times a month to shave once or twice a week. It lasts about 50 minutes per charge, while it also has QuickCharge technology for an accelerated 5-minute partial charge. The current battery status is indicated by a small LED display, which also does not show any extra information. But the question is whether it is necessary.
