Query: The Next Generation Electric Shaver

Although the shaver looks like most of the others out there, the big difference is the unique cleaning system that cleans and sanitizes the shaver. The small amount of solution in the reservoir does the job! Although it needs to be changed out occasionally (every couple of weeks or so), it works very well. The whole unit is designed as an attracting and functional personal care appliance. Daily rinsing of the shaver (just flip it open and run water through it to flush out whiskers) works well between using the charging/sanitizing stand. Yes, it's waterproof so you can just do that. With all the shavers out there, I'm pleased with my choice of the 8160XLCC.
