Great mouse, especially if you're going to be using a PC all day long. Not so much a gaming mouse or anything like that, although i'm sure it would pretty decent for that regardless.

Solid build and should last a long time, which you're going to want if you use your machine for 8+ Hours a day anyway. Both Currys & PC World have these so i'll pop the PC World link in comment one (Just in case that's your preferred, for whatever reason)

So yeah... it might seem quite expensive for a mouse like this, but comfort is everything over long periods. Just like a comfy chair or keyboard palm rest. Find a comfy mouse that is a solid build and you won't regret it. Try in store if you fancy giving it a bit of a road test before hand, after all we all like different things :)
