The Good: Navigating Windows is a breeze with the Microsoft Sculpt Comfort Bluetooth mouse. The wireless connection frees up your USB ports for other devices, its contoured shape gently cradles your hand, and the shortcut buttons will (probably) increase your day-to-day productivity. The Bad: The mouse is designed for right-handed users only, and the glossy plastic finish is a sticky situation in warm weather. Not all features work on Macs and Chromebooks. The Bottom Line: Microsoft's Sculpt Comfort is a dongle-free Windows wireless mouse that delivers superior ergonomics at a rock-bottom price. If you've just picked up a Windows laptop or tablet PC and just can't stand using the stylus, Microsoft's Sculpt Bluetooth mouse is the best wireless solution we've found to free yourself from the cramped restrains of USB transceivers, because let's face it -- sometimes even one dongle is one too many.Logitech has long been the Michael Jordan of wireless mice, offering the best mousing performance for the buck, but the Sculpt Bluetooth mouse is swiftly catching up with some clever features -- like touch-sensitive shortcut buttons and the company's own BlueTrack scroll-everywhere laser sensor -- that makes navigating Windows 8 and 10 environments a breeze. The price is an easy pill to swallow too -- as of the time this was written, you can pick one up at Amazon or Best Buy for under $25, which converts to about \u00a320 or AU$35. First, it's important to note that this mouse is for right-handed users only (sorry, lefties). The shape slopes upward and gently rises back toward your palm, so it's really comfortable to use for long stretches of time. The left side has a trim pad for your thumb to rest.It actually reminds me a lot of the old Microsoft Intellimouse Explorer, in that it's lightweight and molded to cradle your hand. My only design complaint is the shiny plastic finish can get a little sticky if you're using it in hot environments. See that blue Windows stripe on the left side of the mouse? It's both a universal shortcut button and a touch-sensitive touchpad that registers up and down swipes with your thumb.All the buttons on the mouse are remappable once you download the Microsoft Mouse and Keyboard Center software. You can choose to assign the Windows button to do things like open the Start Menu, launch Cortana, or access any of your applications or tasks -- it's really up to you to decide what works best for your day-to-day productivity. Same goes for the thumb swipes, but I prefer to use them to move me back and forward in a web-browser window. Another sweet feature is the mouse provides haptic feedback (aka a little vibration) whenever you swipe it to let you know it's registered the action. You can also disable it if you want.
