We had an article here not too long ago about the SteelSeries WoW mouse, purportedly das ubermaus, replete with glowing fissures and lookin' all like a Templar helmet. We actually had kind of a hard time finding out just how the mouse performed -- it was advertised months before it came out, and it doesn't appear that many gamers actually got to use the mouse prior to pre-ordering it and did so based on Blizzard's official licensing of the WoW name on the product.
The few that did use it, those that played around with it at BlizzCon, actually reported to us that it felt cheap, flimsy, and about to break. That was a bit disconcerting to read, of course, and it wasn't actually an isolated incident--all of the emails we've received about it thus far have been negative reviews. Folks complained of broken buttons or strange key reassignments with the accompanying software.
Now, our sister site Engadget just released their own impressions on the device and they appear to like it, offering a large size, good weight, and robust software among their list of pros.
The inconsistency in reviews of the product thus far isn't what really bothers me, though. It's the fact that the mouse is a WoW-licensed product that performs functions that are against Blizzard's policies.
