The sculpted mouse you get in the package is very similar to the Logitech Performance Mouse MX, but the sculpted shape is a lot narrower and didn't fit our hand quite as comfortably. You get six buttons across the mouse, including the scroll dial, the left and right clickers, a large application shortcut key on the top left, and two forward and back buttons just above the area for your thumb. Again, all of the main buttons are easily configured with the SetPoint software. Finally, there's a small LED battery indicator on the side that blinks when you're running out of power.
One of Logitech's signature mouse features is called "Hyper-fast" scrolling that lets you toggle between a ratcheted and free-spinning scroll dial. The Performance Mouse MX lets you easily switch between the two by pressing a button under the dial, while the MX700's switch is located underneath the mouse itself. It's a hassle to flip the thing over every time you need to breeze through a long document or Web page. Luckily, Logitech makes up for it with the capability to dial-in incremental fluidity, meaning you can adjust the switch to scroll as fast or as slow as you like. There isn't much to say about its performance--the mouse works fine on most surfaces; however, its $80 price tag for the combo means you don't get Logitech newest Darkfield laser sensor that even works on transparent glass and other surfaces that challenge traditional laser sensors.
The MK700 desktop set's truly impressive feature is its unparalleled battery life. Although we don't have the means to fully test out the claim, according to Logitech, two AA batteries will power the mouse for one year, while the keyboard can eke out up to three years if you can remember to switch the power switch off when you're done.
The MK700 is also missing Logitech's new Unifying technology to link with a computer. Instead, it just comes with a standard-size USB dongle that works with both the keyboard and mouse, but isn't transferable to other devices in Logitech's expansive line of peripherals. It's not a big deal unless you already own other peripherals that have the Unifying dongle.
