Another negative is the relatively weak signal from the wireless transmitter. It could not transmit clearly through my wood desk at a distance of approximately 2 feet. This caused garbled letters, doubled letters, or the occasional unresponsiveness. I purchased a USB extension cable and positioned the transmitter on my desk with about 15 inches of direct line of sight. This has been effective, though I have to ensure that I don't put items between the keyboard and transmitter. Water bottles, bowls, or very tall post-it pads wreak havoc until I move them out of the way. My previous Logitech MK700 keyboard seemed to have a better signal and error correction. Though, it also had difficulty transmitting through the desk.
The final negative feature is the lack of special buttons. I used to have an old Logitech MK700 keyboard and mouse and I got used to the volume control and calculator keys. This keyboard doesn't have them, but I was able to map some hotkeys with AutoHotkey and haven't missed them since.
Overall, I'm ok with my purchase. It hasn't thrilled me - mostly due to the weak transmission signal. However, they keyboarding has been pleasant and my fingers feel better for it.

That being said, this is an amazingly solid keyboard for the money. I also own a Das Keyboard 4 and a WASD V2. If I were to give the Das a rating of 95/100 (It's very good), the WASD would get an 85, and this XArmor would get a 93. Its quite sturdy. If you pick it up by the edges and try to twist it, it's just as stiff as the Das and much stiffer than the WASD. The keys are mounted to a plate instead of just the circuit board, and there is zero keyboard flex while typing. Of course, Cherry MX keys are all the same, so the typing experience is indistinguishable from the Das (and the WASD too for that matter).
A couple of things noted by others: The wireless link is rock solid. I have had no issues with range, latency, or dropping. I have the receiver plugged into a front USB port without issue. The keyboard came paired with the receiver. I tried to re-pair it with a Logitech Unifying Receiver (which is apparently only "unifying" for Logitech products) and had some difficulty re-pairing the keyboard with the XArmor receiver. It turns out that how long you depress the pairing button on the bottom of the keyboard is important, and the "Tx" light will tell you how long to do so. That light replaces the Cap Lock light and otherwise blinks every time you strike a key. I don't look at the keyboard while I type, so it doesn't bother me. I also don't type in the dark. If you do either, the constantly blinking light might be an issue.
The lack of a Cap Lock light is a non-issue for anyone who has ever used a wireless keyboard before. Frankly, it's a welcome feature. Because Microsoft Word and other programs auto-correct capitalization errors (turning "cONTINUE" into "Continue" for you automatically) and because the wireless connection is only one-way (from the keyboard to the computer), the Caps Lock light can easily get out of sync with what the key is actually doing. You then have to intentionally make another auto-correct "error" to get them back in sync. Scroll Lock is something that most people more or less permanently leave on or off, so the lack of a light is not a big issue there either. The Scroll Lock light is replaced by a battery life light. My Logitech Trackman has a similar light. It has yet to come on for me, but having a little advance warning that I will need new batteries is a plus.
Finally, if you like Cherry MX keys, then you probably will want to customize your keycaps at some point. Unfortunately, the XArmor keyboard is not laid out in true ANSI standard. Everything is fine except for the bottom row (the spacebar row), which uses the somewhat rare 6.0x spacebar layout. A true ANSI layout uses a 6.25x spacebar where the spacebar is 6.25 times the width of a letter key. Almost all aftermarket keycaps are designed for the ANSI standard where all the keys on both sides of the spacebar are 1.25x in size. On the XArmor, the layout is (from the left) 1.5x for CNTR, 1.0x for the Win key, 1.5x for left ALT, 6.0x for the spacebar, 1.5x for the right ALT, 1.0x for both the right Win key and for the Menu key, and 1.5X for the right CNTR key. You will have trouble finding those keys in those sizes, but they are available. You just have (much) fewer options.
The keycaps that come with the keyboard look fine at first, but they are pretty bottom end (so are the Das keycaps. I bought the WASD without any keycaps). Both the XArmor and the Das come with thin walled ABS keycaps less than a millimeter thick. They both feel cheap. The XArmor caps are technically engraved. The markings look great out of the box, but there's not much to work with, and the engraving is very shallow. So shallow that the white ink, which should be inlaid into the engraving, is more of an onlay. You can feel the ink under your fingertips for most keys. ABS caps are notorious for breaking and getting shiny after exposure to oil from your fingers. PBT keycaps are much better, and they can be dye sublimated.
Wrapping things up, the keyboard is mechanically excellent, and the wireless connection has been perfect. Other than the weird layout of the bottom row and the entry level keycaps, the XArmor was a happy surprise. I use it daily, and have done do since it's arrival. The Das is in its case, and the WASD uses a different switch (MX blues, instead of my preferred browns) so it is only used occasionally. Sorry for the length of this review, but I hope it is helpful.
It fits my needs perfectly as I use my TV as a monitor and my coffee table as a desktop, so wireless is a must for me.
I wanted something for better typing when I have my big projects I work on, but mostly I wanted it because for gaming purposes (what can I say, Battlefield 4 has stolen half my life).
I would say that the biggest Pro is that it is a mechanical keyboard and all that entails (as far as keystrokes not cancelling out at 4 consecutive key presses) but that goes for all mechanical keyboards.
I like the Brown switches. Not that I really had a choice on this keyboard since there is not another version available, but after reading tons on the different colors, I think Brown is what I want the most. There is minor tactile feedback and minor audible click so it just "feels" right to me.
It is probably one of the more "quiet" keyboards, but don't let that fool you. It is louder than a standard non mechanical keyboard for sure. Not by much, but it definitely is.
What I don't like is that there is no Caps Lock Indicator. The sad part is, there could be, There are 3 lights on it. A Numlock light, a battery light, and a transmission light (which only lights when transmitting so it flashes while your type). With a little better planning, they could have room for another light there, or at the worst case share the spot for the transmission light since it only lights half the area. So this would be my biggest Con.
The keyboard also has a rubber type film on it (not the keys, but the board itself and the palm rest). It looks and feels cool but it visually shows every bit of oil that hits the keyboard. So where my left hand rests (as the most frequent used spot while gaming) there is a big shiny palm spot on it. That is after 5 weeks of use. In a year, who knows what it will look like,.
That is a mini con at the moment. It isn't really something glaring as of yet. Maybe over time it will become worse though.
Now the wireless feature...the biggest reason I chose this keyboard.
It is not bad, but it is not what it should be. The range is really short, but honestly it is wide enough for typing. If you are typing you should be close enough to your screen to read it so you should be fine. For gaming I am pretty far back, but still within a decent range and it works.
However, the signal/receiver can get blocked easily. One example was when I was transferring a bunch of paper notes to a Word document. As I finished with one page, I would flip it and stack it in front of the keyboard. Well, a couple pieces of paper on the top edge of the keyboard was enough to block the signal. That seemed a bit weak in my opinion.
But like I said, overall it is decent, and not bad at all. I just think it should be better.
I'd like to comment on battery life, but I don't really have anything to say yet. Having the keyboard with daily use for just over 5 weeks, I can't really say if the batter life is good or bad since I haven't had to deal with it. I know when researching it I wished that the batteries would charge when plugged in via the usb cable, but sadly that is not a feature. However, the 2 cheap, generic batteries it came with haven't died yet so I think replacing the batteries won't be that big a deal.
So that is how I feel about the various features. I know that picking a keyboard is actually pretty subjective to the user and the needs they have. For me, this one is a pretty good choice. Even with my complaints I am not sorry I bought this keyboard and I look forward to it lasting me a long time.
**UPDATE 6/5/14**
The batteries went out recently in May. So I got about 2 months out of cheap batteries and pretty heavy amount of use. While of course we always would like more battery life out of it, I guess it is pretty much what I expected.
After using this for 2 months, I have had issues where I clearly hit a key and it does not register. I'm going to watch this. As it is mechanical, I don't expect the keys to be the issue. For now, I am thinking it is was a wireless issue caused by low battery. I haven't seen it reoccur since I swapped the batteries out, but it didn't "feel" that way while it was happening.
