Query: The best shaver ever

I have used braun shavers for the last 10 years and can assure this is the best ever available shaver. It is quiet, have a battery that lasts for a week, makes a very close shave and, besides all, it is a beautiful piece. The only negative point goes for the case, plastic made, that can easily open and let the shaver umprotected. The older models came with a leather case with a zipper.
