I'm very satisfied with this razor, after I used a number of other different brands before. The workmanship is very good, the battery performance is good sized. The battery indicator is also useful and shows the relatively linear battery charge status to. In many other displays, it is often the case that there is enough in the last still glowing LEDs only for a very short time and the battery is then discharged quickly. The F5800 shaved even in difficult places still quite good. Initially, the skin on the new shaving foil had to get used. After a few days but I was highly satisfied with the result of shaving. There were also no more skin irritation. The razor is a bit louder than my predecessors - but you get used to over time, because the most important for me here was the good result of a smooth shave. Overall a very good shaver with a good price-performance ratio.
