This mirror is exactly what I was looking for - great magnification and the fact that it has batteries means no unsightly cord hanging in my way.  The first one I received was cracked - not Wayfair's fault at all.  They packaged it very well so I assume it came that way from the original factory.  Wayfair immediately shipped a replacement as soon as I contacted them.  

Pros: Great magnification. Very fast delivery.
Cons: Installation is a little tricky - don't assume the holes to install the 'plate' will mean the mirror will be level.  Measure twice, drill once.
