Pros: Characters on keyboard will not wear off — Illuminated keys with color selection — Backlit LCD screen — 18 macro keys with three macros per key
Cons: Only one switch for both keyboard and LCD illumination—Gray WASD and cursor keys wash out characters when illuminated in bright lighting—no USB hub
The macro keys are what shine most on this keyboard. While intended for gamers to record gaming shortcuts, I find them useful for storing captioned URLs I frequently use on forums, oddball characters without having to look up or remember, frequently used phrases, keyboard shortcuts I will never remember or I'm too lazy to type out, etc.
For example, I can press one key to automagically type something like this:
Macrium Reflect Free (here is a good tutorial on how to use Macrium Reflect).
Talk about a time saver!
I frequently use characters not normally seen on a keyboard such as :
There is no way I will ever remember the UNI code for those. Instead, all I have to do is press a key and there it is.
I also have my email address and screen name assigned to single keys.
I also have various computer shortcuts assigned to macro keys, such as the Task Manager.
To program the Macro keys, called G Keys, one uses software that comes with the keyboard (or it can be downloaded from Logitech). One can either record actual keystrokes or copy and paste text into the software. Key programming can be easily reassigned to other keys.
The LCD screen was a bit of a bonus for me; the illuminated keyboard and macro keys were the main reasons I bought this key board (and a spare). It's usefulness is a bit limited, though. It comes with a few basic applets for various display functions, such as a clock, countdown timer, media display, a display showing CPU and RAM usage (the one I use), etc. Some programs have applets for the older Logitech G110 that will also work with the G510s, such as Core Temp. The LCD screen can be read with a little bit of difficulty when the backlighting is off.
There is an attachable wrist rest included but, due to limited space on my desk, I never used it.
Early versions of this keyboard had problems with the space bar but both of the keyboards I have do not have the problem so it apparently has been fixed.
There are some cons that are annoying but do not seriously impact the usage of this keyboard for me. One of the most annoying is one switch is used to turn on and off the illumination for both the key caps and the LCD screen. I really wish Logitech has provided a separate switch for each. I leave it turned off most of the time because of the second con.
The second most annoying con was Logitech making the WASD and cursor keys gray and the characters a clear color. When the illumination is turned on room lighting is also on, the characters pretty much disappear. What was Logitech thinking when they implemented this lunacy? The idiot who came up with this "bright" idea should be shot, then fired. There are other ways those keys could have been made more visible without washing out the characters when illuminated. This may not be a big deal for most people who can touch type but because of my learning disabilities, I have to depend on the scriptural method of typing: seek and ye shall find.
Minor cons included the lack of a USB port on the keyboard. It would have been a handy place to put the receiver for my mouse. Other keyboards I've had had the USB port and I miss it a bit on this one.
Another "feature" the designer of this keyboard should be shot, then fired for is the shiny LCD screen and surround. The flip-out legs for tilting the keyboard up aren't long enough to tilt the keyboard up enough to avoid glare from overhead lighting. Also, the little "bump-out" at the front of the keyboard limited the amount the key board could be tilted. I wound up making some little foam blocks that I inserted the flip-out legs into to elevate the back of the key board and sticking on some little rubber feet at the front because the bump-out on the keyboard would lift the stock feet off the desk, letting the keyboard wobble a bit.
It's a pity the macro keys don't have clear covers on the caps that can be removed so one make custom labels for each key but I got around that (and my lousy memory) by making up a cheat sheet that shows what each key does.
The only other complaint I have is I wish it had more macro keys! I had considered getting a Martian Keyboard but, besides not having room for two keyboards on my desk, the Martian Keyboard has a character limit for each key (including each key's layers) that makes it much less useful. Also, the software for programming the Martian keyboard is klunky to use and does not allow copying and pasting text.
The complaints I have are more than out weighed by the usefulness of the keyboard. The macro keys have me spoiled so much, I will never have another keyboard without them.
