I'm afraid it stopped making any wind after a week and placing it in areas where the blades would fold funnily (plus it was noisy, the blades look very dangerous and had no on and off switch)...
In the end I bought another USB fan, but this time it's different. It's slightly expensive at £7.10 (but I'm sure there are cheaper versions).
This one is like an air conditioner. Unfortunately it is also noisy, but at least there's no blades, it has an on and off switch and hopefully it will last for more than a week! Fingers crossed!
