Reconnecting your mouse every time you switch devices is so yesterday. Pair the HP 635 Multi-Device Wireless Mouse with up to 3 different devices using a USB Nano dongle or pair it with up to 2 devices using Bluetooth. You can even move a document from one device to another[1].The way you work and your ideas are unique and now your mouse can be too. Customize it with 4 programmable quiet-click buttons to trigger specific functions or even different commands within different applications[2]. You can also set scrolling the speed just how you like it – from normal to hyper-fast.Don’t let its compact design fool you. This is one mouse that’s ready to hit the road and go wherever work takes you. A custom-fitted case keeps it protected if you’re on the move and its small size fits easily in carrying cases and bags.No matter how many features a mouse may have, if it drains power quickly, that’s a problem. Rest assured, with a long lasting, replaceable battery and intelligent stand-by mode when not it use, you’ll have up to 12 months of battery life[3] to power through projects.
