Saw this fan at the swimming pool/sports centre the other day. At the top it reads TRASH CAN, which I suppose indicates the lowest setting, and at the bottom, it says MAKE YOUR DAY, which must be the effect of using number 3, the highest setting.
Just in case you’re thinking the titles given to these “settings” are a little random, the name of the fan makes things clearer. It’s called “The Grouad Fan”. Naturally.
