Wow... such a high demand for an out of date mouse. I think I bought mine on clearance for $20 just when they were phased out for the newer versions, and all I wanted was a mouse that fit my hand well and had more buttons. Still use it though... and theres a big paint blemish on the left click button (too many fps games). Yes they are reliable to the person that was asking. I've dropped it on the floor quite a few times and its still been working perfectly for the last couple of years at the least.
