This is a really great keyboard. I will do my best to write a review that addresses any concerns or questions a counsumer like myself may have to help make your decision on whats best for you.TLDR; Great low profile keyboard with a justifyable pricetag.I will break down my unboxing and usage experience as best I could. First off, the item is packaged very well, it has a nice looking box, and there are satisfying moments as soon as you open the package. The board is heavy! You can feel its heft immediatly and you can tell this is unlike any other keyboard you've used in the past if you havent bought a $200+ keyboard before. The full aluminum frame is very attractive and it has a nice brushed finish. The flip down feet at the top corners of the rear of the keyboard can give you a slight pitch, if that is what you prefer.KeysThe keys feel like they are made of the same material, but they may be plastic. The tactile keys have a slight click when pushed in which you can hear and feel. Its worth noting here this is not a particularly loud click and the feel is miniscule as well. If you are looking for a silent press, this is not that keyboard nor is it a loud keyboard if you want that, either.LightingThe lighting of the keys is superb. It is bright and clear. To adjust the colors use the G Hub app. It's a very easy app to use and really well designed. The app has several preset effects like most RBG do nowadays (i.e. rainbow) and there are a few Logitech only settings. I like the ease of use, and per key lighting assignment is dope! The G logo in the top left gives a nice design touch to it. I normally do not like logos on things but it looks good up there and you can easily change that light or have it match the rest of your board.Auxillary keysThe most useful key here, in my opinion, is the "Game mode" (joystick looking) key. This will disable the Windows key so you will never minimize your game when you have a missed keystroke! With this key, in the app, you can assign any other keys to disable when engaged as well. The G keys are essentially F1-9 and they are changed from default in the app as well. The media control keys are self explanitory, as are the other round keys, and the volume wheel is large, responsive and has the same premium feel the entire keyboard has, as well. The round keys are a rubber or silicone with a slight concave feel, also nice.Battery and connectivityI've had no issues with either of these thus far. It is worth noting I do occasionally charge the board, before the battery status goes low. Also I have only used the lightspeed connection and my keyboard is less than 2 feet away from my micro PC. Battery status is displayed in the app, and the connectivity is shown there as well.AppOne of the better designed apps i've used for this sort of thing. You can tell they put a lot of time into this to make your experience as easy and pleasant as possible.ComplaintsI really only have one, and its a personal thing. This is a low profile keyboard. The keys are also low profile and they have like a flat feel to them. If you use low pro keybaords this is a non issue. However, if you are like myself and have only used standard style keyboards in the past it will take some getting used to.SummaryThis is an expensive keyboard, you don't need me to tell you that. I will tell you that the pricetag is fair because of the feel and finish of this item. You immediately feel a difference if you've never used a high end keyboard before, like myself. That being said it wont make you any better at gaming, and will not improve your typing. As far as I am concerned, no keyboard can do that. It will 100% improve your experience and satisfaction while using it, though. If you can swing it financially to splurge on this luxury item, then go for it. If not there are many keyboards that perform the same basic funtions for much less. I hope this review helps if you are on the fence or just browsing.
