What do the students think of Switch stickers?

Student feedback:

"A happy/sad face won't remind me to turn my light off."

"I wouldn't stick that on my light switch and if it was already stuck on I would probably rip it off!"

"A £ sign won't convince me, in halls we pay the same amount regardless of the amount of electricity we use!"

"How does a burnt down tree relate to me leaving my light on? I don't get it!"
