Been using it for a year and a half 5 boxing across two computers. There are two bugs I get from time to time that are annoying. The first is every once in a while a key get stuck, but its usually pretty easy to fix. Its not so annoying unless it is the Control key and then the d key toggles sound on and off for a few seconds until I get it unstuck. The second bug is octopus sometimes crashes when it loads on bootup.
