Bought this for my 2 year old daughter who is totally obsessed with the moon. It's `moon' this, `moon' that... she spends all her time looking up in the night sky for it and the rest of the time spotting it on her favourite TV shows and movies. It was one of her first words. So this novelty light was ideal for her.
The techie bit, in very basic terms: it's battery powered (batteries seem to last forever, so no problem there) and easily wall mountable (as easy as a clock) and comes with a neat little remote control for you to sit back and switch through the lunar phases at your own pleasure. You can choose to have the moon on whatever `lit' position you want, or choose for it to cycle through them continuously. It switches itself off after about half an hour or so.
My little girls little face lit up when she saw it for the first time hanging on her bedroom wall - she needed a new night light and this was just perfect. She enjoys laying down with a drink in the dark and playing with the controller. She will stare at this thing for ages until she eventually drifts away.
One ever-so-slight bad point (is `bad' even a fair word to use here?) As the surface of the moon is lit with a light which is underneath its centre it does tend to look brighter in the middle and dimmer towards the edges. But really, it doesn't matter, and I feel like a goon for even bothering to mention it, but hey, it's an observation. In a darkened room it lights up nicely and the detail on the textured surface really looks extremely groovy.
All in all a very good purchase - especially for my lunar obsessed little monster.
