Braun Büffel Flex Integral 6525

What was Braun thinking when they discontinued the 6520 model? I just bought a 5614, after I found out the 6520 is discontinued and it will be accompanying me back to the stores return department tomorrow! My job requires that I travel 2/3 of my time and I loved the travel lock, integrated 110-240v transformer, and most of all the small size of my old 6520, which I had for 4 years without replacing anything but a fresh charge once a week. The new series of shavers are larger than their predecesors and have a huge power cord that has incorporated a transformer in it ---what does this oversized razor do that the old one did not! They really missed ruined an excellent name!
