I am Electrical Engineer, and have been working in the computer and chip design industry using computers on a daily basis for over 45 years, and this is by far the best keyboard that I have ever used, period. If I had to use one word to describe this keyboard it would be "SOLID". It's a very sturdily built keyboard, so make sure you have a robust desk to hold it. The mechanical MX Brown Keys switches are just "perfect". They feel and sound great, and provide excellent tactile keypress feedback. I have recently tried keyboards that use membrane switches, which felt dead and numb in comparison. I don't think that I can ever return to a membrane switch type of keyboard. These mechanical key switches really do make a BIG difference. There is a much better feel when typing on these PBT key caps vs the usual ABS key caps. The surface of the keycaps is slightly textured which have improved my typing ability. As a plus, the PBT keycaps are sturdier, longer lasting and will not exhibit the well known ABS key cap "shine" that develops over time. The K70 RGB Pro keyboard lighting is just right for my requirements. I just want to clearly see the keys in the dark, so using a static color works best for me. I do not need lighting zones, or fancy lighting effects, and as such I did not download or use the iCUE software used to do this. The very nice thing about the K70 RGB Pro keyboard is that you can control the basic lighting effects (minus the real fancy ones you need the iCUE software for) on the keyboard itself just using the Fn key. Even in max lighting setting, the K70 RGB Pro keyboard lighting is subtle and does not blind you like some of the other recent keyboards that I have tried. The angle profile of the keyboard is also ideal, not too low or too high, it is just at the right angle with the feet swung out. I need my keyboards to have a palm rest, and so I was concerned as to the stability of the detachable one on the K70 RGB Pro. The palm rest magnetically snaps to the keyboard, and there are two mechanical plastic tabs that keep the palm rest from moving from side to side relative to the keyboard. This results in a very solid palm rest that seems to be built right into the keyboard. The surface of the palm rest is not smooth but textured which makes it much easier to use. The palm rest is hard plastic and not soft padded. I personally prefer that since I think the surface of a soft padded palm rest would eventually crack and break. I am not a fan, and never use the "Windows" key on a keyboard. On past keyboards I have been frustrated by the occasional accidental pressing of this key when trying to hit the "CTRL" or "ALT" keys around it. The K70 RGB Pro keyboard has a "LOCK" function key that is used to disable the "Windows" key which works perfectly. So the accidental "Windows" keypresses no longer happen when using my computer with this keyboard. Another key that I will occasionally accidentally press is the "CAPS LOCK" key. On the K70 RGB Pro this results in a nice bright white "A" light getting lit on the top status panel. Other keyboards I have tried just lit a round LED sometimes hidden just above the arrow keys on the bottom left side, which made it hard to notice. The only negative I have with the K70 RGB Pro is that I wished they had made the "A" light just a tad larger and red so it would be impossible to miss. The audio control buttons on the upper right side of the keyboard are just your basic media buttons, which is all I need. The most important ones are the mute and volume scroll wheel which work just fine. The K70 RGB Pro has three additional features that I do not use: 1) keyboard macro recording, 2) a tournament switch, and 3) a removable USB cable. Perhaps I'll find a use for these features somewhere down the line. Before settling on the Corsair K70 RGB Pro, I recently tried and returned the Razer Black Widow V3 and Razer Ornata V3 keyboards. The Black Widow keyboard had mechanical switches but they were very sensitive, the palm rest tended to slide sideways, the lighting was very intense, and the key cap surface felt way too high for my taste. The Ornata uses membrane switches which felt completely dead and offered no tactile feedback, the palm rest also liked to slide sideways, and there seemed to be a sea of background light surrounding the keys, which again was way brighter than what I was looking for. I found that I made a lot of typing errors on these keyboards when compared to my old Logitech G213 keyboard. In conclusion, the K70 RGB Pro is a well built keyboard that seems to check all the right points. It even helps to make this poor typist feel like he's a world class typist.
