Given the amount of time we all spend sitting at computers, it's never too early to pay attention to your daily ergonomics -- because, well, #wellness. You can stave off the impending doom of repetitive stress injury just by switching up your typical usage patterns, so take a second right now to survey your workspace.
If it's time to upgrade your mouse to a design that follows the natural curve of your hand, the Logitech Marathon Mouse M705 will make your joints happy for less than the cost of a few lattes. It lists for $50 in the US, £45 in the UK and AU$80 in Australia, but you can find it online for $36, £36 and $AU59.
Your wrist should never be the pivot point for mouse movements so Logitech designed the M705 with a smooth contour that skews slightly left so your elbow does the work instead. The top surface is wide to accommodate a range of hand sizes but if you're looking for something bigger, the company's flagship MX Master Mouse is so big and comfy that it feels like a Lay-Z-Boy for your hand.
The mouse has six extra buttons in addition to the standard left and right clickers on top. You get two directional thumb buttons on the side that move you "back" and "forward" in a web browser or media player, a hidden button underneath the thumb pad on the left and three separate buttons on the scroll wheel that engage by clicking left, right and down.
The mouse works via plug-and-play as soon as you insert the USB dongle but -- on Windows PCs, Macs and Chromebooks --you can also install Logitech's SetPoint software to re-map the buttons to commonly used tasks like opening applications, navigating media or engaging shortcuts like full screen video. (The M705 will also work with Chromebooks, sans the custom software.)
One feature that stands out on the M705 is its speed-adaptive scroll wheel that lets users toggle between smooth and notched scrolling using the button on top. I generally prefer to have a notched wheel that navigates down a page click-by-click, but the ability to switch to a free-scrolling wheel is perfect for jumping back to the top of a long page with a flick of a finger.
