Microsoft Mobile Mouse 4000
While there are plenty of wireless notebook mice around, that hasn't stopped manufacturers attempting to try and innovate. Microsoft's latest attempt is the Wireless Mobile Mouse 4000.
It's a wee little nipper - 61mm by 103mm - but despite its size it's relatively comfortable. Rubber grip pads on either side hold your hand in place, while your fingers rest on the smooth upper surface. In the middle of that surface is a black panel with a Microsoft logo, battery indicator and the mousewheel.
But not just any mousewheel. Imagine coating yourself in vaseline, then getting in a bath of baby oil, then slipping yourself between a set of the smoothest, most silken velvet sheets you can picture. That's what using this mousewheel feels like.
Of course, what that means is that gamers will hate it. There's no definition between clicks - it's one fluid motion. Flicking between weapons will be irritatingly imprecise. Though, to be fair, gamers aren't exactly the target audience for this product.
Along with left and right clicks, the mousewheel click, and the ability to click the wheel left and right to scroll in those directions, there's also a fourth button positioned forward on the left. Unfortunately, it's just out of comfortable thumb-reach, but that's not too big a deal.
The sensor seems accurate and responsive. It was able to track with only a couple of very minor glitches on the surface of a glass desk that we tested it with. On a mousepad, it was very quick so if you find you need a bit more precision, it might be worth dialling that down a little in the settings.
The sensor is miniscule - so small you might lose it - but luckily it slots into the base of the device for when you're travelling. The mouse also has a hard on/off switch so you can save battery if you're not going to be using the device for a little while.
Microsoft's latest iteration of its mobile mouse is great. It's compact, smooth, and full-featured. The only criticisms we could level - like comfort - would require a full-size mouse to rectify.
Available for just £25 at the time of writing, the Mobile Mouse 4000 is a great investment for a regular traveller that's fed up with their cramped trackpad.
