Great keyboard that's programmable and has big buttons and good backlighting

This works very well and even beats out the 360 chatpad.  The buttons are bigger than on the 360 and the backlighting is great (especially at night).  It fits snug.  Has all the volume controls there.  Even has a couple programmable buttons that be mapped to features or to launch apps.  Note that you can't use the standard Xbox One headsets.  You have to use headsets with the regular 3.5 mm plug (which is why the chatpad comes with a new headset).  They say it works with Windows 10 but haven't tried that.

This is my first mechanical keyboard. I had no idea how loud the keystrokes would be, but I don't mind it at all. This keyboard seems to be built really well. It feels substantial and feels very nice to use. The color changing backlit keys look great. You can dim or brighten the backlighting or even turn it off if you like. you can also change the direction of the light fade from right to left or left to right. You also can choose a single color.

Amazing for the price! The keys are very tactile and clicky. The backlighting is really cool, and there are a few cool modes that you can use. Only problem, the backlights are not programmable. In other words, the colors that you see in the picture and the keys that have those colors are what you get. You can change the colors to match a theme you may have or what not. Overall, great keyboard if you're on a budget.

I got the Blues, and after a week I have to say this is a joy to type on.

My last keyboard was a G510 and that was good for 4+ years, but I didn't need all the extra macro keys. I was looking at the Corsair, and Ducky Shine boards, but was ultimately scared off by all the complaints of corsairs compatibility issues, and not being able to find a Ducky Shine in stock for a reasonable price.

No software, just plug and play, great feel, nice sound while not being annoying and overly loud. The media controls are fantastic.

Honestly, the only complaint I have is that the LED's for the Num / Scroll / Caps lock are bright in a dark room.

3 month edit: Best keyboard I have ever owned. I will purchase a second if anything happens to this one.

I sometimes use the computer in low-light and dark situations, so having a backlit keyboard seemed like a good idea.  This Azio keyboard is wonderful: three different backlight colors, large-labeled keys, and a very good feel and sensitivity compared to other keyboards I have used over the years.  Due to the large labeling of the keys, this should also work well for many people with poor vision.

EDIT: I like this keyboard so much that when I bought and set up a computer for my mother for Christmas, I replaced the computer's standard keyboard with this one - my mother and my sister (who actually installed the computer) were both very impressed with this keyboard!

I just received my keyboard this afternoon, and I am very pleased. The keyboard illumination has several levels, colors, and zones. When you have separate colors for the keyboard zones, you can also change the illumination colors and brightness. The materials and construction was also a pleasant surprise. The plastic does not feel cheap, has a sturdy feel, and also is a bit hefty for a keyboard. The extra USB port and the Mic/Headphone jack is also a nice touch. Key push and weight are right on par, and you can't feel a noticeable difference in texture between the plastic and metal keys - so typing is still smooth.
The touch controls for volume, brightness, etc can be a little irritating. It works well almost all of the time, but sometimes you have to "mash tap" to get them to work. Also fingernails and such do not work on those buttons. Other drawback would be the interface to create macros (the 12 "C" buttons)
If I had a choice between the new G15 and the Saitek Cyborg (having used both) I would take the Cyborg. While it is nice to have the little screen on teh G-15, the function and style of the Cyborg are superior.

I would give this 4.5 stars except for the insane fact that Esc requires the Fn modifier key.  This is due to their decision to default to the specialty keys (i.e. home, cut, copy, paste, back, play, forward, etc) instead of the F1-12 keys, and including Esc in this arrangement.  Del(ete) mercifully does not require the Fn key.

Everything else about this keyboard I love!  The battery life may be a bit short, but it hasn't really bothered me over about a month of use.  It does take ~5 seconds to wake up after the first keypress, but this is true with most wireless keyboards, including the apple bluetooth keyboards I've used.

The variable color backlight is unnecessary but fun - I wanted backlighting but did not need different colors.

The typing/key action feels great actually, and that is the main reason I got a keyboard after all.  If that hadn't been so excellent, it wouldn't have mattered how nice everything else is.

I am a fan despite the Esc key nonsense, and I use Esc a *lot*.

Unlike many keyboards I've tried out, this one is actually comfortable to use and is an excellent nighttime/gaming keyboard.

They keys are very very quiet and not click/bangy compared to some other high end KB's. The brightness is good in an absolutely dark room (even with a monitor in front of it) and I actually like the 6 macro keys compared to the previous ridiculous amount of macro keys in the prior model.

The LED screen is handy but not a requirement. It does add a nice feature to keep track of things when you're gaming but I would have liked to have seen more apps developed for it making it even more useful. The LCD Studio software is pretty buggy and not user friendly at all.

The added gaming list which automatically adjusts the LCD screen on the keyboard for critical gaming information is great and gives you plenty of feature stats at a mere glance instead of having to stop or look something up. Mine has the orange display but I would have much more preferred it being all green instead. I've seen the blue and it's way too dark.

I've had no issues as far as being able to use it with any computer and it connects without having to add any of the included Logitech software. Although the keys are plastic your fingers actually compress and stick to them very well despite their glossy appearance.

One thing I didn't like is if you take the keyboard apart to add vinyl film (for coloring), the LED screen seems to not want to hook up even with the filament connection positioned correctly. If you're thinking of modding this keyboard you better consider it seriously as you may not have any use for the (then) dead LED screen :(.

Other than that though I liked this keyboard much better than the Razer version and much more over the Saitek version. I do like the fact Saitek allows you to change the LED colors on the keys though.

Finally a keyboard you can use for those dark, lonely Friday nights home alone on the internet, LOL! No, but seriously, this is a pretty good keyboard. It's priced a bit high, though. I'd have liked it if it was ten dollars cheaper.

The Caps Lock sometimes has issues and it gets inverted, meaning the Caps Lock light will be on, but type lowercase instead of uppercase, and vice-versa. This sometimes happens with it. The keys themselves are a bit big and bulky and sometimes, you have to press down hard in order to type. I'm typing this review up using this keyboard right now. The keys being so big and not-very-sensitive to keystrokes like other keyboards can be a negative to some, but is a positive to big or tall people with large hands and fingers. (I'm not one of them, though.) It's not as easy to type with and you feel like you gotta really poke the keys down. I wouldn't recommend it for Word documents or homework. It's good for light internet surfing and anything that doesn't involve long-term typing. You'll get about two paragraphs in before you're sick of the extra pressure you have to exert. Unless you're a giant, like I said.

One minor gripe is that the keyboard's LED lights are ALWAYS on. There is no way to turn the lights off. Having seven different colors is nice, but the eighth option should've been to cut the lights off for when using it during the daytime. It is always illuminated, unless you unplug the keyboard entirely. During the daytime, this can be annoying. Also, if you have a gaming computer, I wouldn't recommend this. The bulky keys likely won't respond in time to whatever game you're playing. Unless you're a heavy key-masher, this is best for non-gamers.

All in all, it's a good keyboard and does it's job. A bit over-priced for a third-party brand, and not very good for fast and/or professional typers like myself, but it's worth the purchase if you want a cool, future-modern looking keyboard that glows in the dark and has seven colors.

Back light is awesome, keys sound like some laptops with the built-in keyboard but I like that. I have never had to press a key twice, and overall liiks nice. The palm rest is nice as well, however it's not removable. The only keys that don't light up are the space bar, Print screen, and pause/break buttons. Other than that, I have had no problems with this awesome simple looking black keyboard.

I like the large font letters, the feel and especially the light - you can change the color and the brightness level to suit your needs.  Solved all my keyboard issues.

The Code 104 is an excellent mechanical keyboard. I like the backlighting especially in a white color - I am not a gamer and prefer the more functional white as opposed to a wilder color like green or red. Having seven modes of adjustability is also great as sometimes I don't want it too bright. The keyboard is clicky with the Cherry MX Blue switches but I was expecting that. I added the dampener o-rings that WASD also sells and they have made it quite enjoyable to type on and a little less noisy. I do find that there is a 'ping' sound that I hear from the keys every once in a while. Hopefully this does not become annoying or louder over time. It is a very well made keyboard, very sturdy and supportive with the rubber feet extended. This is actually my first mechanical keyboard and I can say I am never going back to a rubber dome again. I am using it on a Mac computer and everything works seamlessly, having no OS specific keys is nice as I think staring at the windows key would bother me. I highly recommend you try WASD.

This is a really nice looking mechanical keyboard that feels great to type on. The lights are a huge plus and have a pulsing or continual glow (whichever you choose). These switches are loud but if you are looking at mechanical keyboards, you probably already knew that and are okay with it.

As a keyboard, this thing is awesome.  The keys feel great and the sensitivity means I am typing this review faster than I could have on other keyboards I have owned.  The backlight is absolutely essential as the keys are very difficult to see with it off.  The WASD backlight feature is nice for gaming assuming you use that keyboard set.  I wish you could change the keys that are backlit... but alas it is either all, WASD, or none.

Two things... the first is only a note...  It is possible to accidentally change the backlight settings with the keys on the keyboard.  When I did that it turned off the backlight and I could not reenable with the management software... Second... the programming application for macros and other settings is rich and robust.  I am sure you can do a lot with it... It took more time to learn than I really had... its full featureset makes it complicated.

They have done an amazing job with this keyboard that I am typing with right now. The LED's are nice and bright, but not too bright, I usually keep it on the highest setting, but my workspace is pretty dark so I like the light to kind of illuminate the area. The keys are sensitive, which some may not like, but I find easier to type with and good for gaming, because it makes it easier to slide across the keyboard without worrying if you pressed it hard enough or not. The keys aren't so sensitive that it presses if I lay my hand on it, so it still has enough resistance. The keys are not very spaced out, which some may not like, but they aren't any smaller than an average sized keyboard. The number pad and arrow keys though are spaced perfectly, my old keyboard had the arrows touching the shift, enter, and control keys, I hated that. It made it too hard to keep from pressing another button when playing shooters. The keyboard also looks good with the light off, I thought the keys would be junky see-through plastic to allow the light to shine through, but color wise, it's as solid looking as a mac keyboard. The black around they keys is stylish, and doesn't seem to be to much of a finger magnet, despite its reflective surface. The silver edge around it looks good too. The back also has two flip out pedestal stands, so if you don't like your keyboard laying flat, no worries! The wire is long enough, though not particularly long, long enough. maybe, 4 1/2 FT? I am pretty bad at estimates though. This keyboard is great and I recommend it to everyone, especially for the price! I would say this keyboard is worth around $50.

Got this after watching an MS Tech video, this is a fantastic keyboard at this price. It is amazing that they are able to make something with this much quality and functions at the price. I't looks like a much more expensive keyboard then it really is. The  switches aren't cherry but for most people they should be fine. I definitely prefer the size and aesthetic of this keyboard over the Corsair Strafe I was using. The Corsair is a good keyboard, but this one suits my needs better. I'd say the blue switches on this aren't as good as the cheery blues on the corsair for gaming, but for typing they work pretty closely.
