The Good: The Logitech MX Anywhere 2 is a rechargeable wireless mouse for Macs and Windows PCs that offers smooth, precise operation, lots of customization options and decent ergonomics for a mobile mouse, and works on almost any surface. You can connect to up to three computers using Logitech's included Unifying Receiver USB dongle or opt for Bluetooth connectivity. A speed-adaptive scroll wheel lets you autoshift from click-to-click to hyperfast scrolling. Battery life is good. The Bad: Ergonomics aren't as good as on Logitech's larger MX Master; the rechargeable battery isn't user-replaceable (but should last several years). The Bottom Line: The MX Anywhere 2 is a top-notch mobile mouse. Logitech's MX Anywhere 2 Wireless Mobile Mouse is essentially a mini, travel-friendly version of the company's flagship . This trimmed-down mobile version retails for $80, though it can be found for closer to $60 (\u00a365; AU$130) online.I tested the MX Anywhere 2 with both Mac and Windows laptops. I like it a lot, though ergonomically speaking it isn't as comfortable to use as the MX Master. That said, it's about as comfortable as you can expect from a smallish mobile mouse that's designed to easily fit in the side pocket of your laptop bag. And it's a nice weight at 3.7 ounces (105 grams).As you might expect from a high-end mouse, it has plenty of bells and whistles. Thanks to Logitech Dark\ufb01eld Laser technology, it works on just about any surface -- everything from a glass table to the Formica-style finish of my work desk.It has an integrated rechargeable battery that's supposed to last up to 60 days on a single charge, which is almost double the battery life of the MX Master. You can continue using the mouse while charging with a Micro-USB cable, and just 1 minute of charging gives you 2 hours of usage. I wasn't able to precisely test battery life, but I haven't had to recharge it in the three weeks I've used it.
