25 years Brown ..... and there are better. After my battery Braun was technically at the end after 5 years I came by a recommendation on this model from Panasonic (to 3 months Free Return Policy). The price for the comparison model of Braun about twice as high. The Panasonic reduced my shaving time from the start to 1/3. He is absolutely skin-friendly and fortunately even waterproof. Although I do not use it in the shower, but cleaning is optimal. The short charging time of about 45 minutes for about 10 days shaving is a hit! My recommendation: try ... and be amazed. I use the shaver for over a year and now I have also given my father the model!
