This is a feature rich keyboard that can be not only for gaming but your daily driver of computing. It has many features that other keyboards in this class does not have. The keys are very responsive and they do have feedback when you press them. They do not click like most mechanical keyboards but are similar to the MX Brown type switches.
It has 9 macro keys and 3 memory banks for a total of 27 macros you can program either on the fly, or within the Logitech gaming software you download from logitech. It also has ARX which you can use to watch system stats, control your media, see your macros and do various things that you can use on your smartphone or tablet. And you can set your phone in the ARX Dock on the top of the keyboard it does not charge the device but keeps it within view.
The RGB is not super bright like other rgb keyboards and is pleasing to the eyes in the dark which is a huge plus. It is worth getting if you want to have a quiet keyboard if you are looking for a clicking keyboard this is NOT one as it has ROMER-G keys on it. It is not super quiet like membrane but it does send feedback to your fingers when you press the keys so it is great for general use besides gaming.
