Good Idea but Bad Performance.
I shave once every two days and decided to try M3 Power Nitro (black). It attracted my attention by innovative idea of combining regular razor with electro-vibration, thus making a hybrid.<br /><br />I'm not impressed with it at all! I don't like it for several reasons. Vibration actually is mostly reflected on a handle so I felt uncomfortable because it was making my hand too shaky and I'm 26 years old and not a drinker! It doesn't cause cuts or burns but it felt really annoying to my hand while shaving and even a few minutes later!<br /><br />Due to a better lubricator-strip it glides better, softer than regular Mach3 but shaving performance is about the same. Handle grip is OK but a bit worse than regular Mach3 because it doesn't have fully rubberized handle bottom.  It can be used with Mach3 cartridges, I tested and shaved. While shaving I was concerned about not getting wet its battery compartment.<br /><br />I would rather use it as regular Mach3 razor, with vibration turned off, but would NOT buy another! Why pay more for a "fancy" but in fact useless/annoying vibration function if regular Mach3 does practically the same, if not better, job?!
