Great little gadget. Very simple but robust. Believe me, i've been using these for 7 years now. They're great for fixing inside a box or a project case. It takes two batteries (they come with the device). One interesting point is that the batteries are connected in parallel for longer lifetime. You can take one out, it keeps on working.
