Most wireless keyboards use RF instead of the clogged 2.4GHz band, which sits WiFi, Bluetooth, your microwave, and many other devices. Not i-Rocks though. It has 8,388,608 unique IDs to differentiate the keyboard and the mouse from other wireless devices. It also comes with a USB dongle that stores inside the mouse.
The keyboard is also a “laptop style” keyboard with “laptop style” switches. This means it’s much quieter than normal keyboards, so fans of the IBM “clack clack” keyboards should stay away. The keyboard takes AA batteries and the mouse takes AAA batteries.
