Great, replaced Microsoft natural 4000
Great key placement, performance, noise. I used a Microsoft ergonomic natural 4000 for over 10 years (still going strong), but I decided to try a separate numpad. I'm loving it! The negative tilt is just right. The size is awesome. I think I am even typing better without all that extra keyboard! I can place the numpad on the other side of my mouse, and I am so much more comfortable. The numpad is not perfect for me: it's a bit wide, doesn't have 00 key, backspace or tab key. I'm still enjoying it though. The wrist pad is hard, but the leather is comfortable. I've developed a little callous on my right palm as the Microsoft has a cushioned (but worn and peeling vinyl) pad. Overall, really enjoying this keyboard! (35 hours a week)

Perfectly balanced Ergo keyboard with a brilliant split keyboard approach for easier mousing
Finally, real engineering thinking went into an ergonomic keyboard. I love this. It's the right price. The reason I bought this one was the price, but I was hoping for the best. The simple design logic of splitting the main keyboard from the extended numbers pad is brilliant. It seems so obvious. First of all, people hunting for ergo keyboards also use keyboard trays to make sure their elbows at the right height -- and most of these aren't that wide. This design solves the problem by splitting off the numbers pad -- now you can move it in when you need it without forcing your mouse hand far to the right in an bad ergonomic zone. Simple, right? So why don't more keyboard makers do it? I bought their matching "handshake" mouse as well (the vertical kind -- it's very good too.) Is it ergonomic? It is for my hands (normal sized male hands). I saw one person complain about keyboard click, but I don't notice anything. I have mechanical keyboards, which are far noisier. This one is slightly clickier than a logitech, but way quieter than a mechanical. It's perfect for me. The keyboard layout is good, except I'm a Mac user, so the Windows key I had to train myself to think of it as the Mac Command key -- I just had to force myself to use it. It's counter-intuitive. I like that it's rechargeable on USBC -- charged quickly, and havent' had to recharge so far in heavy use (I type about 10,000 words a day). Highly recommended. I like the faux leather hand rest better than a spongy memory foam style (like Logitech's ergo keyboard, which I have as well -- those foam ones are softer but get dirty from sweat, cat hair (in my case, since my cat likes to sleep on keyboards), etc. I like the faux leather feel and style. Thumbs up all round, except the stupid Win Key, and I think it's a mistake to have the power button on the bottom (Most people probably don't turn off keyboards, but I do, otherwise my cat will be sending emails to people.) .

It's great! For my use case at least
Ergonomics: 10/10 Portability: 10/10 Modularity: 10/10 MAC/PC compatibility: 10/10 Connectivity: 7/10 - no bluetooth connection unlike the EK01, this needs dongle connection Button feel: 7/10 - the EK01 feels so much smoother to press. This feels like a silicon-based keyboard, leaving it feel a bit cheap. Why did I choose it over the EK01? Because the first 4 of the metrics mattered more to me. If you have table room to spare and don't mind the size, EK01 is definitely the better choice. I, on the other hand, am used to TKL keyboards, so I prefer this one despite the drawbacks. You just got to find what works for you.

This is good. Super useful moving the Num pad out of the way
This is the most comfortable keyboard I've ever used. I also have ProtoArcs mouse which is amazing. Typing is smooth, fast typing, easy to travel with, an most importantly, it's strong.

Pourquoi je ne l'ai pas acheté avant!?
Je regrette d'avoir passé toutes ces années sans. Bien qu'une adaptation pour réapprendre à taper est nécessaire, la position des mains est tellement plus naturelle et cela enlève beaucoup d'inconfort et de tension. De plus, avec le clavier numérique séparé (que je me sert constamment) je peux le placer de l'autre côté de ma souris et c'est merveilleux. Ce n'est plus a moi de me déplacer pour travailler confortablement. Aucune difficulté a faire fonctionner ça a été du "plug and Play", la batterie sans fil dure très longtemps. Et évidemment l'ergonomie est respectée. Un investissement qui vaut la peine sans aucun doute pour ma part.
