For device:
The plastic feet can be bolted to the walls or ceiling, where I've just screwed onto a small wooden board to make it added. Unfortunately, it is the front so hard that stands upright only on the glass lens it when you turn the lens upward. If you want to project the light spots on the wall would have to screw it somewhere or just reinforce the ground, it does not fall over.
The disco light work with battery and was after inserting immediately functional.
The light has 2 modes: 1. slow change of the light spots (not too slow not too fast, is harmonious and peaceful)
2. Fast change of the light spots (Disco-feeling)
The light is also relatively light and throws the light points also across the whole room still on the wall.
Have made a few pictures of what it looks like.
For 10 absolutely fine and highly recommended! (:
