Logitech V550 Nano Cordless Laser Notebook Mouse - Logitech V550 Nano
For those of you who have not read our extensive reviews of the Logitech Cordless Desktop MX5500 Revolution or Logitech MX Revolution Mouse, Hyper-Scroll is the company's brilliant innovation in scroll wheels. It allows you to switch between traditional notched scrolling (brilliant for gaming) and free-wheeling no-resistance scrolling that's perfect for navigating long documents and web pages.
Using the easy and intuitive Logitech SetPoint software you can adjust most aspects of your mouse, including assigning any function you wish to the buttons. Thus, if you tend to use 'middle-click' often, just assign it to the Document Flip shortcut.
Much like that found on the of the Logitech G9 Laser Gaming Mouse, the V550 has a large button on the back that releases part of the frame. This reveals the battery compartment and dongle cradle. Battery installation is incredibly easy; however, while it's great being able to store the dongle inside mouse, it would have been better if Logitech had followed Microsoft's lead here and gone with an indent like the Microsoft Wireless Laser Mouse 6000 v2 that didn't require taking the mouse apart to store the dongle.
On the bottom is the metal retention mechanism for attaching to the dock, the switch which automatically turns the mouse off when docked, and a separate on/off switch with its own LED indicator. Meanwhile, three Teflon pads ensure the V550 glides smoothly across your desk.
The last standout feature of the Nano is an incredible 18 months of claimed battery life! Yes, you read that right, under normal usage conditions this amazing little critter ought to give you 547 days of use before the juice runs out. Obviously, I could not personally verify this claim - unless you fancy waiting over a year for this review - but if it even comes close it's still astonishingly good.
The problem with the Nano V550 is, as is often the case, a rival product: its older sibling. If you're not sold on the whole 'docking' idea and can live with changing the batteries once every half year, then Logitech's own VX Nano offers better ergonomics, a more stylish look and extra buttons, in addition to a protective carrying case - and can be found for less online.
While it's certainly innovative, the idea behind the V550 Nano's 'notebook-docking' will be somewhat impractical for many and looks a tad ugly. And though it's a great mouse on its own, unless you really want the claimed 18 month battery life, Logitech's VX Nano is probably a better option.
