Four very different mice have made a visit to our desktop.  We've looked at two gaming mice, and two mid-sized mice, partway between those specially designed for laptops and traditional, larger ones. 

Crazy idea or a useful innovation?  The A4Tech 4x3Fire is a mouse for gamers that includes a built-in fan that pushes air onto your hand to keep it cool and dry.

The Oscar, another A4Tech mouse, is no less surprising.  But where on earth did they get the inspiration for its style?  Once you've actually got hold of it, it's actually remarkably efficient!

The Trust ComfortLine Wireless Mini Mouse is as stylish as the classiest of Logitech's mice, but it's three or four times cheaper than the one that it looks like, but it doesn't share all of the characteristics.

Our final mouse claims to be something of a record-breaker: the Logitech M705 claims a battery life of three years.  But does that make it a great mouse?
