It's a mirror and does its work. I expected it to be smaller, but that's not a real problem. What bothers me a bit is that the metal support isn't very firm, so it doesn't stay in position properly and the mirror tends to slide a bit.
It halso has a led light, but no instructions included. It isn't rocket science, but you have to figure out by yourself how to have access to the battery compartment (just turn a bit the opaque ring and then you can unhook the metal support; this allowes you to open the mirror and insert the batteries).
