Summary: This keyboard is great. I have been a Logitech user for many years and just upgraded from a basic keyboard to this G105 gaming model. The macro buttons are great and easy to assign and use. And the windows lockout key that disables the windows button from working is great too. I have accidentally hit that button before with my palm, so it's definitely a plus.
Summary: I've always loved the feel of the Logitech gaming keyboards. Logitech gaming keyboards just have a certain feel and touch to the keys that no other brand does. I personally prefer the feel of Logitch gaming keyboards. This one is no different. The keys actions are smooth, responsive and snappy. I used to own I G110 until I spilled coffee on it and picked this one up as a replacement. Even though it is the lowest model it suits all my needs for gaming.
Pros: The keys have a good feel to them. I actually like that the WSAD keys are a colored the same as the arrow keys-- I use them so much for movement in games, so it helps a lot. Also, there are not so many extra function keys on the side as a lot of Logitech's previous offerings in this category have had, meaning it will fit more keyboard drawers.
Cons: The keyboard itself is much lighter than my old G11, and it doesn't feel quite as solid and sturdy. The two light levels in the key backlighting are barely distinguishable from each other. The game mode switch, rather than being a physical switch, is simply a button that you press to toggle game mode on and off (i.e., deactivate the windows keys). And finally, the media keys and volume control are operated by using an "FN" key (like a laptop keyboard).
Summary: Overall, a very nice keyboard, I like it, even after all those cons, they still are only enough to remove a single egg. Though, to be honest, it doesn't offer me much of an upgrade over a standard "normal user" keyboard. I think I could have benefited if I had gone a step higher or so to say, the G110 or something. Still, if you want a really solid backlit keyboard with programmable macros, this still has some application for you.
Pros: -Function keys. There are 6 of them. I haven't programmed them in yet.
Cons: My qualms are sparse and relatively minor...
Summary: the g105 is a really good keyboard,really love the LED lighting on this thing which is really good for gaming in dark rooms like me.the G buttons are quite good as well,useful multimedia keys.a good upgrade for me.but i do agree with some people saying that this thing needs a few tweaks.but overall this thing is amazing and happy that i bought it.
