I've had this for so long, I don't even remember when it came into my possession. It requires two AAA batteries. The power doesn't turn on easily, but it does if you press the power button repeatedly. It seems to turn on more easily if you tap the camera body. The screen on the back does display something, but it flickers a lot. I haven't tried taking any pictures. There are many scratches and stains. This is a junk item, so no warranty is provided after purchase. Please understand this before purchasing.
