The MX900 looks exactly like the MX700. This comes as no surprise since it really is a MX700 - with a Bluetooth transmitter. The mouse is one of the best looking mouse I've ever seen, with seamless integration of it left and right mouse button and very classy two tone paint scheme.
The MX700 features eight programmable buttons to make navigating a webpage or game a lot easier. Like the last Bluetooth mouse we tested , the MX900 is for right handed users only and Logitech has no plans to ever make a left handed version.
The underside of the MX700 holds the optical engine, a connect button to wirelessly connect to the Bluetooth charging station, two rechargeable AA batteries and copper recharging contacts.
There mouse moves along your mouse pad on five small pads. The pads are no bigger than the recharging contact but they provide a very smooth surface for the mouse to glide on.
The MX optical engine emits a low glowing red light to track mouse movement. The engine itself is very precise, making the mouse ideal for graphic artist and first person shooters. Battery life is not as good as the MS IntelliMouse Explorer for Bluetooth but that shouldn't be a big issue since the batteries are rechargeable and never needs replacing.
