My oldest grand-daughter is a huge Dr. Who fan. She has quite of few of the items from the show. I was looking for a little something for her stocking and came across this.  There's a try me button on the side that you press and  it lights up. It's a really cute little thing that looks so real. It's not bulky so it will go well on her keychain. The little light seems to be bright enough for her to see the door lock on the car at night. Heck, she can just put it on her desk and admire it.  I was going to say play but she's 22 years old so I'll stick with admire.
It came days before it was suppose to that's a big plus too!
