Vorneweg I want to write a praise to Amazon. I got the premium shipping chosen, this has unfortunately not quite work and the keyboard came two days later than originally planned. But Amazon has specially called me and apologized for what I think is very very good, do not all online merchants - hats off.
The new G15 has in my opinion a much nicer than the old design. It is symmetrical, and I liked the keys even better. The keystroke is a bit tighter than the old. The oragene lighting is a matter of taste - I like it just as well as the blue, some other like the blue better, as I said a matter of taste. A plus for the orange light is that you do not have to make an effort so the eyes as the Blue (detected by PCGames hardware). Also only 6 G keys are present, what I myself find much better, as the G15 is thus nothing around so brawny and thus also fits on smaller desks. The keys are otherwise exactly the same as the old, except for the media keys: I find a lot better as the old. There has been much easier access to the keys and also like by design me the new media buttons much better. The new display is also a matter of taste, I need for my part not such a big screen, so good enough for me of the G15 Refresh Edition and also likes.
Conclusion: The new G15 I find is a huge success. It is not perfect and has some shortcomings, but do not bother me. A reason to switch from the old to the new, there is not any event - provided you have not made even his old broken. From me anyway there 5 Star. I hope I could help you.
