Summary: This keyboard is amazing. I play music rhythm based games like Stepmania and openitg which are timing based so input lag is a HUGE no no in my book and this keyboard does NOT dissapoint at all! Absolutely no input lag and the awesome "clicky" sound the keys make from the mc blue cherry switches is GREAT! I previously ordered the tournament edition of this keyboard which felt like it had a slight input lag.
Summary: I really love this keyboard. Kind of pathetic, yes, but I actually bought this keyboard for the sound. I love the clicks that the cherry mx blues make. I do a lot of RTS gaming, and while I am not going to say this keyboard does anything insanely special, the profiles help a whole lot for hotkeys - making things a lot quicker & easier.
Summary: First off I would like to say that this is a great keyboard as far as they go. This is my first mechanical keyboard and I love it. Others who are more familiar with this type may not agree, but from a newbie's perspective it's a solid buy. I will be brief with my review since I don't know much of the lingo behind mechanical keyboards and their types of switches, but I can highlight some of the pros and cons. For starters, I will say the keyboard is indeed loud.
Summary: I have the older blue LED style version of this keyboard at home and love the feel so much I bought this one to use at work. Obviously has an addicting feel and had to ask myself why I ever got away from mechanical keyboards. However as nice as these keyboards are, both keyboards suffer from some sort of sleep bug where when it comes out of sleep it's like the enter key is held down. Very irritating and forces me to unplug and replug the keyboard.
Summary: If you're not in close quarters with other people who don't like keyboard sounds, these keyboards are amazing. My only mild complaint is getting used to where the Escape key is can take a few days. That, and sometimes you'll accidentally hit the "program macro key" button and mess up a few things. If that happens, just go into your Razer settings and remove that macro set. Those are my only complaints!
Summary: The Razer Blackwidow Tournament Edition keyboard is amazing, i love the satisfying click that you get when you type because of the cherry mx blue keys (but remember it can be loud so keep that in mind before you buy it). It's amazing for gaming, very comfortable and all around i am so happy that i bought it. The keys are laser engraved so you don't have to worry about the letters rubbing off.
Summary: I held off writing this review so I can do a full review on the keyboard itself, I ordered this keyboard (Used, from Amazon Warehouse) on 4/24/13, so far I have no real problems with the keyboard. I really do enjoy typing and gaming on the this keyboard it's nice and sturdy. I've switched over from Arctosa to this keyboard and I can feel the difference. The Cherry MX Blue switches are very smooth, very responsive.
