Braun Pulsonic 9595 Electric Shaver

I have had a number of Braun razors over the years and they've all been the best of the best: Best shave, best ergonomics, best overall design and very reliable. However, you had better hope that it doesn't fail. A friend of mine bought one on my recommendation at Xmas time and it failed after about 20 minutes of use - and I believe this was just a fluke - but what's disappointing is that it's more than 4 months later and they haven't repaired it yet. He's had 5 telephone calls, filled with endless excuses and even a promise of a new razor but it's mid-June now and he still doesn't have either the new razor or his old razor back. THIS IS TOTALLY UNREASONABLE.
