This is my third purchase of this type of Braun shaver. The batteries died on the first two, and it worked out cheaper to buy a new one than have the batteries replaced. You cant do it yourself due to the Torx screws that Braun use. I have tried the twin bladed Brauns, but this single blade version shaves me better. The fact that I am on my third model should tell you that I rate this model. The other bonus, is that this model can be used straight from the mains if the battery is dead, unlike the previous model I had.
Very good service and the shaver does everything it claims to. Very pleased.
Great all round shaver
