i have a razer deathadder at least that old that still works perfect. perhaps you have a defective one or it was dropped. its nothing to see a mouse work for 5-6+ years.
do yourself a favor and just buy a cheap $5 cloth/rubber-foam mousepad. anything else is just throwing money into the wind.
the only real suggestion would be a logitech g-series mouse. personally i wouldnt go with a mouse made by a company that doesnt specialize in perepherals.
