I owned a BW for nearly 8 months last year, it was my first mechanical keyboard, I used a newegg gift card and bought it while it was on sale for about 50 dollars. It was a good keyboard, I don't know why it gets so much hate. The only cons I have seen from it were the glossy finish and non standard keys, which other keyboards that have these downsides don't get nearly the same amount of bashing.
It seems to be the "cool" thing to bash razer products, and I can't help but feel some people who are the most vocal about it have not even owned a razer product..
Maybe I am one of the lucky people but I have no hate for razer, I had that BW for a long time, longer than I have owned any other mechanical keyboard and there weren't any problems with it. I didn't necessarily care about it one bit, I never cleaned except for when I sold it and the only thing that happened was there was some nearly unnoticeable wear on the WASD keys and a tiny scratch in the glossy finish that was like that out of the box if I remember. No defects, no build quality issues, nothing. I also own a deathadder, I have had it for about a year and it still works perfectly, I have taken it apart numerous times and sanded it down after the "black edition" rubber finish started wearing down.
I don't hate razer products, but I wouldn't say I love them either. Their products aren't nearly the best out there, but they are far from the worst, if you can get some of their stuff on sale, it is great.
