As far as I can tell it is not mechanical, I don't know if that matters to you, but just incase you didn't know, now you do. I used to have that same keyboard but my version had a LCD like the G510 (Forget the model type, they stopped making it). I absolutely loved it. Back lighting was great, but not to bright that it would annoy me. Awesome multimedia controls, the switching from game mode to windows mode was nice. I like it, unless you want a mechanical.
