I don’t always use cartridge razors, but when I do, I prefer they vibrate.
The Pace Power accepts any of Dorco’s blades, included the seven-blade options mentioned above. If you’ve ever used one of the Gillette Power models, you know that the vibration (surprisingly) makes a big difference in mitigating irritation. Or at least it does for me.
With this addition there are few reasons, if any, to go with a competing cartridge brand.
