Completely worth the money. Really they are worth more than what you pay for but most likely it would be intimidating paying more for a keyboard without knowing. After 4 years there is literally zero wear on the keys, these DO NOT wear and have the light bleed through a big hole where your wasd used to be. Keys still have the amazing response they did when I purchased it. Also, within the first week or so I spilled a full glass of water into the keyboard. I dumped it out and waited a day, and never had a single problem. My brother owns the green edition and has the same thoughts. Just ordered another one for a work computer. If these guys ever go out of business, I want to know ahead of time so I can buy 10 and die with one of these. (bit drastic?)
Just a quick note, it takes a day or two to get used to how the keys feel. All other keyboard feel like a joke now.
EDIT: Keystroke is consistent all the way through, so what ever keyboard that is, that's what I own.
