Now we really have seen it all. We thought we had witnessed, unpacked, tried, tested and destroyed all of the USB-compatible gizmos and devices on the planet. But we were wrong. And the wonders of Universal Serial Bus technology never ceases to amaze us.

Having seen a tribe of USB-compatible mug warmers, slippers and all manner of heat-inducing devices, now it's the turn of a new generation of cooling gadgets to help one chill out at one's desk. So now's the time to cool it and take a chill pill (in a strictly metaphorical sense, you understand).

Looking for all the world like a standard desk fan, this miniature version provides a chill blast of Arctic air into one's visage, de-stressing and de-misting on even the most humid of deskbound August days.

Despite its digital pedigree, it has old-style analogue controls at heart. For swift and efficacious operation, simply plug into the handy little USB port on one's computer and deftly flick the switch on the front. And there. Instant relief from global warming. For about 20 years.
