i-Rocks RF-6570 wireless keyboard/mouse

Most wireless products eliminate the clutter and mess of wires, but they do introduce a new problem – too many devices that sit on the 2.4GHz frequency band will start to overlap one another, with the signal getting cut off completely at times. The i-Rocks RF-6570 2.4GHZ Keyboard and Mouse combo eliminates this problem by utilizing the 2.4GHz FHSS (Frequency Hopping Spread Spectrum) and bandwidth detection technology that offers over 8,388,608 sets of unique IDs, making it almost impossible for the keyboard and mouse to be affected by other RF products. Both the keyboard and mouse are powered by a pair of AA and AAA batteries respectively. Does anyone care to share how they solve their RF woes other than purchasing products with FHSS technology?
