Review (1/5): Flimsy and cheap: don't buy this if you plan to use the USB cord to power it
tl;dr: Don't buy this if you plan to use the USB cord to power it it.
With gentle usage, the USB port broke: upon plugging the cord out and back in, it got stuck / fell off unside the mirror. It's impossible to take apart to fix because of several springs that are glued strongly in between the mirror and the stand.
