mine is a roccat pyra (too small i know) but its not high end it has just one year and it feels like 5 or more years old. some parts has glue and it unstuck and the wheel and other plastic parts are waste, you can see the mark of my hand on it. Although mine is gaming wireless (sounds like contradiction) and sometimes get desynchronized and i have to pause the game... another thing is that it has a software to change dpi and those things but if you change it from default mode it gets crazy 11 not usefull.
for all those things im thinking to buy the steelseries to try.
