This thing is useless. I mean, technically, it's a mirror, but...
The mirror itself is pretty solid. It's not of the greatest fidelity and water seems to sit on it rather than run down. The anti-fog stuff works as advertised.
Unfortunately, that's about all the good I have to say about this thing. "Wall mountable" is a bit of a misnomer. As far as in shower use, don't bother. The suction cup doesn't stick to much of anything. I tried tile, fiberglass, wood, laminate...when it did manage to stick, any faint disturbance of any kind (even looking at it funny, it seems)would cause it crashing to the floor. The only successful surface was my big vanity mirror, which seems a bit superfluous. I don't really need a shaving mirror on my vanity mirror.
