Speedlink Ax on

Research has shown that we’re more prone to illness and infection during extended periods of intense study, when we’re pushing ourselves hard and straining our immune systems. Add a germinfested computer mouse into the mix and you could be headed for a cold or tummy bug. Reduce your risk with the Speedlink Axon, a five-button USB mouse armed with an anti-bacterial coating that kills up to 99 per cent of bacteria. £29.99, speedlink.com
