It is worth the buy. I love that the globe does rotate on its own at a steady pace. It can stop rotating, but because of the magnetic force it will likely start again. You will need the lights on, because the magnet, while working on its own without the power, cannot have the "spaced," magnetic hold without the power plug inserted. Overall, great product and very motivating to be able to see the world rotating in your own room. And it is motivating to be able to feel the world within your grasp knowing you may have a chance to help change it for the better. Thank you.
