How cool! It’s really apparent that so much thought went into the design of this mirror. It does plug in, so you will need an outlet nearby. I was pleasantly surprised at the length of the cord (it’s wrapped up and clipped behind the mirror), and as I went with the over the door option, install took about 5 minutes! Its really pretty, and even included adhesive padding for the bottom to prevent bouncing off of the door when in use. The colors are bright, and the touch screen is super responsive. It’s substantial but not heavy. I’m really excited for my daughter to discover it in her room!
