Query: great

its very quiet. it doesnt lag, actualy the software even speeds up the mouse's movements. range is good. i could type this from my bed because it allows me to zoom in and it works 6 feet away. i tested it up to 30 feet away and it still worked. the presets are awesome except the ones that are set up for websites, dont work with google chrome. other than that my only grudge would b the small size of the top extra buttons. ive already typed 44002 characters and still counting. the alarm can be useful. i have very keen hearing and if its late and theres not a sound in the house i can actualy hear the mouse transmittin the signal. my last mouse it was only audioable if u put the mouse to your ear. also the mouse is tinier than my microsoft wireless explorer but i got used to this one. overall great
