I've had mine for about a year and a half now, it isn't the best quality, but it hasn't broken (totally) yet.
I had to fix the spacebar, the right side stabilizer popped out of the key stem, made the switch really rocky and eventually the stabilizer worked it's way under the m and n keys, causing sticking. I fixed it by shooting some epoxy into the stem and sticking the stabilizer in. I haven't had an issue with it yet.
The software is crap, it won't remember the settings, and each time I reboot I have to re-select what profile I want (even when it is set up to be program specific).
The glossy surface sucks, so I used plasti-dip on it, not the best solution, but it was cheap and has held up reasonably well so far.
The Blackwidow at least got me into mechanical keyboards, so I can thank it for that
