Bests & Worsts Reviews from Amazon

This is a great mouse. One of the best ones I have ever used. Some of the features I really like: - The (newer) nano receiver, which can stay on the laptop at all times. - The wireless just works. No pairing issues, no long initial wait when turning on. - The "anywhere" part which is true! This mouse works on absolutely anything. - All the buttons you need on a small mouse - The great dual-mode scroll wheel for step-by-step scrolling or fast flowing scrolling. - Good ergonomic despite the small size. - Easy on/off switch at the bottom, which doubles as a protection flap for the sensor. - Nice pouch. All of this said, I am instead using a Logitech VX Nano Cordless Laser Mouse for Notebooks (Black). I don't think one is clearly better than the other. Choosing one vs. the other is a question of personal preference and priorities. Here are the main differences: - The VX Nano is quite a bit lighter (by 30-40%) and it makes a noticeable difference. The Anywhere MX is a bit heavier to begin with, but more importantly, it uses AA batteries vs. AAA for the VX Nano. Note that despite the larger batteries (about 2x capacity), The SetPoint software is predicting ~100 days for the Anywhere's AA and ~150 for the VX' AAA, so I guess the new "dark field" laser uses 2-3x more power. I thought of using AA-AAA adapters to keep the weight difference down, but that would drop the battery life to <2 months. For me, that was the biggest deciding factor with the next bullet. UPDATE: I have since discovered that the Anywhere MX can work with a single AA battery, which IMHO keeps the weight more reasonable. - The VX Nano is quite a bit cheaper. Now that it's not the "best" Logitech laptop mouse, its price has dropped quite a bit. While the Anywhere MX price is pegged close to MSRP, the VX Nano's price is oscillating up to 40% cheaper than the Anywhere MX. That's a big difference. - The Anywhere MX can be used on any surface. In comparison, the VX Nano can only be used on most surfaces. It's still extremely competent and works on fabric, many shiny surfaces... anything you'll normally find in a home or an office, and is much better than old red LED-based mice. It does not, however, work on transparent surfaces. If that's important, then the Anywhere MX is the only option. - The VX Nano has the back/forward buttons on the top vs the Anywhere MX on the side for the more traditional thumb access. Advantage Anywhere MX here. Those top buttons on the VX Nano are not great and I think that was one of the main complaints. I am glad Logitech listened. - The on/off button on the Anywhere MX is easier to use (flap to slide vs. hold for 3 seconds). - Both mice get a pouch. The VX Nano has a mesh pouch that's a bit baggy. The Anywhere MX has a tight smooth pouch. It's a near tie. - The VX Nano comes with a USB extension with holder to use with a desktop. The Anywhere MX doesn't. Not a big deal IMHO. - The Anywhere MX has the new Nano receiver that can support several devices. The VX Nano has the "old" one. They are the same size though and behave identically with a single device. In particular, there is no pairing and initial latency issues as seen on Bluetooth devices.
