The mirror is great!  The light is quite bright and I have no problem with the on/off switch so I have no idea what others are talking about when they say the light is too dim and the switch is slippery - I found neither of those to be an issue.  I only rated this product 4 stars because installation is a bit "trying". The screw holes didn't line up exactly and it took some strength to hold the base in place to make them align. Also, the screws are brass so easily stripped if you aren't careful. Once in place though, the mirror is terrific - just what I wanted!
