Summary: Fast delivery. Very expensive but in the long run, cheaper than razor blade. Definitely need to replace these every 6 months for a smooth shave without the razor burn. Works great with replacement. I recently started to use soap lather and find that it works so much better than regular shave cream because the soap lather brushes on so much closer to the skin.
Summary: Hi, Have had this razor (ES 8249K) for 4 years - no problems even with shaving in the shower every day. Th razor is always getting soaked - Panasonic's engineering with this has been first rate imo. Last month the shaves were not as smooth so I begrudgingly bought the replacement foil and blades combo for $50 - expensive - but has transformed the razor back to like new condition. The shave is faster and closer as compared to the older foil and blades.
Summary: My Panasonic razor was not getting the job done. With the new blades and foil, it is working again. I didn't love spending so much, but I was able to make the original set last for several years. These seem the same and might last too. That would make the cost per year $25 or less, and that isn't too bad.
