Stand-by buster plug
Around £40 of your electricity bill goes on wasting power with electrical goods left on standby. While the most obvious thing to do is physically turn off said items at the plug socket, many of us are too lazy to tackle this.
Thankfully, all of your items can be properly turned off at the touch of a remote control which turns off all of the items it's connected to with a push of a button. This is a great gift for a cash-strapped student.
