I have a wired Cherry Blue keyboard that I use at work and I love that keyboard even though it's noisy. I was a bit worried about getting this one with Cherry Brown keys, but it didn't turn out bad at all. It's still a great mechanical keyboard and I can type much faster on it that the other mushy keyboards. My laptop's chiclet keyboard drives me insane with tons of mistakes, but with this wireless keyboard (which now sits on top of my laptop keyboard) has improved my accuracy and speed tremendously. Most people probably don't worry about ghosting (pressing multiple keys at once and having them register). So I tested this and it behaves a little strangely. If I type press the keys a, s, d, and f all at the same time, they register (great!). But if I try g, h, j, and k, only one of the keys register. q, w, e, and r will register all at the same time. z, x, c, and v, too. Basically, certain combinations on the left-side of the keyboard will register. This might be great for gamers who might be prone to press multiple keys at the same time.

There are 3 blue LEDs: A Tx (Transmit) LED which blinks every time you press or let go of a key. It was kinda cool at the beginning, but now it seems kinda useless. Too bad I can't turn it off. There's a battery LED, but I've not seen it turn on yet after 2 weeks of on and off use. There's a Num Lock LED.

Pros:
Mechanical keyboard (I make less mistakes and type much faster)
It's wireless! I've measure the distance up to about 10 feet. It didn't make sense for me to go beyond that given that I can't see clearly what I'm typing at that distance from a laptop or a desktop.

Cons:
I wish it was the noisier Cherry Blue keys, but that's just me being picky.
I wish it had a Caps Lock LED.
I wish there was a way to turn ofd the Tx LED.

As a general rule, I type a lot every day. I am a programmer and I play online multi-player games like Left 4 Dead 2 and Borderlands. I use this keyboard for both uses. It's a quality keyboard with few frills.

First and foremost this is a mechanical keyboard. If you want a quiet, lightweight, gentle, don't-break-me-bro keyboard this probably isn't your kind of keyboard. On the other hand if you need a stout keyboard you can use day in day out, which won't skitter across the desk as you type, and won't wear out in a year or two, this keyboard is good.

The key-press is a little hard; however, not overly so. This isn't a membrane keyboard. It has tactile feedback. This keyboard uses Cherry Switch MX Brown mechanical keys which are a much loved in the mechanical keyboard world.

This keyboard has a very useful feature. You can run it wired via USB or wirelessly without a USB cable. The best of both wired and wireless worlds. You only need the cable when running without batteries or batteries when running wirelessly.

I can recommend this keyboard for home or office use, though in either environment it is important that you understand the keyboard is not quite as quiet or lightweight as cheaper membrane keyboard and doesn't have all sorts of bells and whistles.

I use this with my desk top replacement laptop. I had a Logitech Dinovo for Notebooks keyboard which was fine, but, it had a tendency to fall apart. The keys would slip off the scissor springs that kept it off the membrane. It was quiet, but, unreliable.

The U9W is perfect. Not cords. Well, they give you a cord, but I haven't had to use it. The battery life seems very acceptable. The keyboard does go into sleep mode, which is good since there isn't an on/off switch to conserve battery life. The keyboard wakes when you tap a key and an unobtrusive LED light turns on. Another LED lights up whenever a key is tapped. The third is a battery indicator, I guess it lights up when your batteries are low in energy. I haven't seen it turn on except when it wakes. By the way that is a good feature. Like the LEDs in your car, they should light up when you start it up, to verify that it will illuminate when you need it to.

Anyway, the Dinovo is a better keyboard for portability, no doubt. Small, light and quiet. You can travel with the Dinovo. It's small enough to put into your laptop bag without taking up too much space and it has an on/off switch. The iOne Armor U9W is not that keyboard. It's more of the opposite. I wouldn't travel with it without removing the batteries as, it will wake if anything depresses a key.

The keyboard is a bit quirky, I have to say. There is a place to store the USB micro-dongle. But, it's just for storage. It would have been nice to see a switch that shuts the keyboard off, when stored. I have a Logitech mouse that does that. It's a nice feature. Adding this feature would resolve battery drain issues with the travel.

The other thing that is quirky is the attachment of the palm rest.

I've tried several different setups for the wireless on this keyboard and I could only get reliable performance if it was 3 feet away or less in line of sight. Otherwise it periodically dropped off and produced gibberish. The good feature of this keyboard is the Cherry Brown keys which you can get with another keyboard. Tried to get vendor support, no luck, they are not supporting this model. Finally, it would not run on the USB cable, (and yes I have powered USB). I returned it to Amazon and went through a couple of keyboards before settling on an excellent DasKeyboard. (Unicomp also makes a very fine keyboard if you like springbuckle keys.)
