Very nice.... but that key that changes the color of the keys is needing a smack down.

Nice keyboard guys... very nice :)

Excellent!

This keyboard is everything I wanted and more. Went from a MS 4000 to this and whilst it took a few moments to reposition my left hand homerow (due to smaller keys and the extra programmable keys), I'm in love. The feel (and sound) of the red switches are lovely. The RGB is a nice touch as well. Absolutely recommend.

Garbage parts

My original keyboard worked for 2 years and then one day began spitting streams of garbage characters out making it impossible to use. Then I bought a replacement. It worked for about 3 days before the "W" key just failed. When I contacted Support, they asked if I had used update firmware on a brand new keyboard... when I clearly described a problem with a dead switch underneath the "W" key. I expect better out of a keyboard that costs 2-5X what other keyboard cost.

A few nits but great if you're going blind.

I bought this key due to an eye condition that made it hard to identify keys in the dark - which is when I do most of my work. I also was getting tired of my old keyboards having the ctrl or other common keys fading away over time even thought the hardware integrity was intact. This is especially true with "chicklet" laptop keyboards.
Cloud Nine was the only actively lit keyboard I could find, and for the purpose I bought it for, it is perfect.
There are a few downsides though with my model
The keys, though more natural than some is a little too tight, meaning the keys are a bit too close together for my hands. This causes me often to hit the wrong key like caps-lock instead of A which gets annoying.
Also, finding the home keys is not quite as easy as say on Microsofts old natural keyboards which I have used for decades.
But the really big nit I have to share is the M10 key which just happens to be close to the left ctrl key. If I hit that, the keyboard key color scheme changes.
This would not be so bad, except when I do tthat, I have to cycle through about 32 other schemes to get back to where I was.
This is incredibly annoying when one discovers that the M10 key is the ONLY key you cannot re-assign. Perhapse a firm-ware updatte could fix this.
The color scheme isn't something a heavy user would want to change all the time or often. It needs to be just a little more out of the way, like use the M1 key instead which will not be accidently hit so easily.
Ohter than that, this keyboard is bullet-proof and fairly ergonomic.
I hope Cloudnine reads this review and makes the needed changes to achieve a 5-star rating from me.

Ergo TKL is the best keyboard ever - Now go make a separate Ergo TKL Number Pad Please!!!!

Can't say how life changing the Ergo TKL is - I've had hand surgery, and although the outcome is great, the recovery is awful. Only thing that could make my typing world better is a number pad with the same padding as the TKL
