i have read reviews of the laser mouse they say "its too damn sensitive". at first i wanted to buy that combo but i ended up with a lx700 because i cant find the mx3100 here in cebu. where do u plan to get it or order it? i saw tti selling the laser mouse alone it cost 4800 i think or close to that price that's only the mouse. i got my lx700 for 4800 both mouse n keyboard i have no problems with both keyboard n mouse.
yah i think the difference between the bluetooth n rf is only the range but m not so sure.
