I have a Razer BWU 2013 edition - the one with the green backlight - and frankly, I think it's a good board. People claimed that the key cap sucked but if I compared the key cap with the one from WASD Code, they are the same. I guess all backlit key board have to have a key cap that is coated and laser off the print for the backlit to shine through the alphabets. The green backlit is evenly lit and is attractive, to be honest. Sure, the additional 5 macro keys on the left column is gimmicky but it's not that bad, really as it's just one column of keys and they used the same size key caps, unlike some which uses smaller caps making it feel like an after thought. This keyboard is also matte instead of glossy, which is a great improvements - at least the listen to their customers, unlike Das, which still refused to move away from glossy keyboard.
The BWU is very heavy. There was one tear-down post I read and the reviewer was impressed at the quality of the metal plate they used and how they have firmly secured the cables to the plate. I'll see if I can find the post if anyone is interested.
So, I am not sure why the negativity Razer BWU is getting if Das and Code was acceptable to many. I think their popularity was the bane. People just hates successful companies (e.g. Microsoft.. ) ha ha ha..
