I don't like Razer's quality of keyboards.
I got a Tarantula Keyboard, which was their old flagship model, and have had nothing but problems with it. I can't comment on the Black Widow, but from my experience I would avoid. When you pay a high price for a product you expect top quality, which i didn't recieve. I even asked for a few replacement keys because the letters were rubbing off, and the response I got is "We don't supply replacement keys for this keyboard". Brilliant service there.
Razer mice = Good
Rest = Crap
My 2c.
Well, I can say the BlackWidow feels amazingly well built. Obviously haven't had it long enough for the keys to start eroding so I haven't had to ask for new keys yet.
OP, yeah if you don't like those macro keys then stay away, horses for courses and all that.
When my mate (the cola spiller) used it all he did was complain that he thought the bottom macro key was the CTRL button and it just annoyed him. Funny how he "accidentially" split coke on that very key!!
But since my last keyboard had the same row of keys (sidewinder x8), I'm used to it.
I use them in quite a few games too. I normally use them as an extension of the number keys that I can't quite reach easily (6,7,8,9,0).
