Not the best keyboard ever
599423
CONS: Its more of a learning curve than I had hoped.  The special keys don't provide any value, I often click them thinking they are the regular QWERTY keys.  Caps lock is wayyy too close to the other keys.  Its unlike any caps lock placement Ive ever experienced.  Im constantly clicking it by accident instead of the "a" key.  The illuminated keys are insanely bright even on the lowest setting.

PROS: Special keys COULD provide value even though they haven't yet.  The feel of the keyboard and typing is nice.  I can see why peoiple like mechanical keyboards.  It doesn't feel cheap at all.

I was a little disappointed with this key board as it has some issues.
1. The backlight is only red or blue, the purple changes back to blue after a few moments if not immediately. Purple is desirable as it is easier on the eyes.
2. The function keys are intermittent. It is hard to get into the BIOS when you must restart twice until the keys decide to work.
3. The multimedia keys do not work, as in no volume or mute. Not a killer but somewhat irritating.
I contacted the seller on 18 October and have received no response.
I would have purchased this locally but nobody carries it anymore and now I think I know why. It functions better than my old one and good enough that I will use it till something better comes along. And for the price you still can't beat it, lowest price large print keyboard I have seen.
 P.S. As I write this the lights have decided to stay purple for now, we will see for how long. Whoops just changed to blue, oh well.

I've had this keyboard for a little more than a year.  I type more than most but not as much as others.  I don't live on it or anything is what I'm saying.  And yet a lot of the labels on the keys have worn off (a,s d, e, k, l, m...all disappeared or are illegible)  That's disappointing.  Strangely I use the numpad a whole lot and all those labels persevere.  The zoom slider gets sticky.  It should be spring loaded so that it goes back to its neutral position after it is used.  But those are my only two complaints, really.  I'd never used an ergo keyboard before so it took some getting used to.  Maybe a month or so to be really comfortable with it, but once you're comfortable you're more comfortable typing than you probably ever have been.  Even though it's not perfect I've been very happy with it and I don't even use most of its features.

This is a fairly good keyboard, but there are a lot of issues I have with it. For starters, the keys are a little difficult to press (you have to push harder than I'm used to). Another problem I have with it is that it runs out of battery with the backlight on full quickly. So the wireless feature is fairly worthless. A related problem to this is the plug to charge the keyboard. I believe it is a mini usb connection. It doesn't use batteries like most wireless keyboards. The backlight isn't very bright, and for some reason it defaults to turning the backlight off after something absurdly short like 5 seconds without use. I can't remember the hotkey, but you can set it to stay on longer, but imo it should default to the always on setting.

Well the action on the keyboard is garbage! and its a bit slow.  Really its a computer for under 200 dollars I guess you cannot expect much.  I only use it for infrequent work trips so for that's its ok but if your going to be using this thing more than once a week i would consider other options.

It looks nice, but the keyboard doesn't work that well. and the whole bike rocks when you use it.  not really as good as described. I wish it were.

the keyboard is OK.  I guess I'm just used to the micrsoft comfort keyboard with the hand rest.  I personally do not like the chicklet style keyboards.

The keyboard is large and cumbersome. I get the whole "ergonomic" thing but I don't know why they have to be so bulky. It works as designed I suppose.

update: Keyboard did not last very long.

The keyboard size is nice, and the spacing between the keys is great. The lack of a numbed is alright, It fits on my keyboard tray much better than my previous keyboard. Backlighting is kind of lame because there colors are fixed and cannot be changed, only the brightness changed. the amount of light they put out is alright though. the mechanical switches are alright but far from the best. just alright.

Keyboard isn't the best to type on.  I should have bought a different one.  The mouse also freezes a lot on this.

not a good keyboard. feels cheap. the buttons take some getting used to, the enter button and shift button are way different than the oem keyboard on my laptop.

The biggest down side to this is how close the keys are together, it doesn't feel that comfortable when typing but is negligible when gaming - perhaps even allowing you to reach that number 7 key a lot easier. I imagine that this is because of the extra keys on the left side. I've had multiple mechanical keyboards and this one performs exactly as it should. The lighting is NOT customizable per key, you'll be forced to have the left control, left shift, wasd, arrow keys, and numpad arrow keys lit unless you turn the lighting off. The light is a white light shining through the key face and it's light strength can be customized, as well as an interesting "pulse" feature that.. is just distracting, really. Overall, not the best keyboard due to its weirdness, but a functional and pretty one nonetheless.

Space Bar got stuck many times... buttons mushy. I ended up spending a little more for a Corsair K70 MX blue mechanical keyboard. That is the best keyboard I've ever used.

UPDATE 3/9-16

As I originally rated lower, they actually contacted me saying that they would do anything to gain my trust again which is mind boggling.

Great price, but very clunky...keyboard feels cheap and not very fast

The keys are slightly too close together for comfortable typing and they don't offer much tactile response - they're somewhat mushy and they move around a little which gives you the impression of a cheaply constructed device.  I expected a better feel from Logitech.  Finally, the context menu key has been eliminated.  In its place you will find an over sized FN key which activates the second function on the dual function keys.  You can still get the context menu, but you now have to strike two keys (FN-PrintScreen) to activate it.  For anyone who uses context menus extensively, the extra keystroke may be annoying.

I type for a living (40+hrs a week) and this key board is ok but you are better off getting something a little higher quality. The keys are really loud so if you work in an area in close proximity to others it becomes annoying to them. The wrist pad is not a wrist pad at all it is actually hard and the whole keyboard is sort of hollow so when you type fast and furious (like me :) ) it echos loudly.
