Have I bought this because my shaver Philishave predecessor broke down after 8 years. It is worth noting the progress in noise reduction. The 6940 is very quiet and the shaving heads have become even more flexible. Was important to me when choosing that this model does not have a battery and a problem with that part is omitted. When traveling, no problem, works from 100-240 volts. He shaved skin gently and thoroughly, is easy to clean (brush included) and is thoroughly recommended. This strike price necessarily. Buy !!
