Shaving while in the shower is something that many people do.
It can be difficult when you can't see exactly what you are doing but this fogless shower mirror will help you get it right.
To use the mirror you need to add warm or hot water to the built-in water chamber.
This is easy to do because you are in the shower anyway.
Once you add the water to the chamber it is scientifically impossible for the mirror to fog.
The glass is shatterproof so you do not need to worry about dropping or knocking the mirror.
