To make oneself a number of buns and others a little sophisticated or elaborate hairstyles, until then, to see the back of my head, I was trying to take a portable mirror on a stand in front of the sink mirror .
By installing this one next to the mirror in the bathroom, for me the main mirror 35 cm and height of the face (ie being able to see the whole face without the guide up or down), it allows me to direct it behind my head and see what I done easily, but also by pointing ice of any cm, I can also see the sides of my face and check for example if my makeup is not missed (eg etblàforme side of the eyebrows, the rendering of blush on the cheeks, though I have no brand like "orange" before the ears because of the foundation, or even realize I even slight contouring and check the sides of the temples, the oval face, nose etc ...
This also serves to men, for example, to see their loan face for shaving, and myself your myopic, with the magnifying side, it allows me to put my lenses without having to stick my face in the main mirror.
Now I realize how much it is convenient when I'm not home and I try to see the sides and back of my head in vain!
I hesitated a lot before buying this mirror for fear that it will harm was decorating the bathroom, that this burden this one too, and the idea of having to make holes in the floor, so with the risk of a break but knowing that if I changed his mind would remain visible and no return!
And to help other potential buyers, with several single layer of transparent stoch on the floor before making the holes with the drill, it helps to dampen vibration and avoid breaking the tiles!
