Logitech Wireless Mouse M505

The latest mouse in Logitech's seemingly endless line of input devices is the Wireless Mouse M505, a $50 portable pointer with an attractive design that comes in three colors: black, gray, and red. It's also one of the first devices to feature Logitech's Unifying technology, which allows you to connect up to six devices including keyboards and other mice to the same mini-USB transceiver. The technology promises to free up USB ports for other devices, but it also means that you're marrying into the Logitech family. The mouse is accurate and comfortable, but for $50, we're disappointed by the lack of thumb buttons. If you're looking for a no-fuss wireless mouse to throw into a laptop bag and run, we'd recommend the Microsoft Wireless Mobile Mouse 4000, which offers many of the same features and more for $10 less. The Logitech M505 is similar in size and shape to the Microsoft Wireless Mobile Mouse 4000. It fits comfortably in both hands and there are slotted grooves in the clicker area for the ring and pointer fingers. The scroll wheel in the center of the two buttons is notched (as opposed to smooth), which allows for more precise scrolling through a longer Web page or document.
