Fab travel mouse, I'd even use it as my main one. Huge battery life, I've been using mine a lot over the past 6 months on the same battery. Great feel and responsiveness. Cheapest I could find for the red one. It's been a couple of quid cheaper on HUKD in the past but still a good buy. Website blurb below.
