FAQ:

How much space does it take up?

Being small form factor, the footprint is quite small.  Compare it to a multi meter:

Do I have to use the "GND" connector?

Most of the time, probably not.  Some projects may require earthing, and as such a ground terminal is conveniently placed.

Can I connect my earth strap to the GND connector?

Absolutely.  The terminal is perfect for hooking up your anti static wristband when working with static sensitive components.

Are the leads easy to replace?

The power supply has industry standard connectors; 4mm banana jacks at the front, and a PC type connector at the back, as found on many appliances around the home, like gaming consoles, computers, media centers and, of course, personal computers.
