This is pretty much exactly what I’ve been looking for.
PROS:
• Super comfortable!
• Sturdy, weighty and feels well made.
• Modern low-profile responsive keys
• Perfect angle split design.
• Tilt legs in the front so it tilts backwards not forwards like 99% of keyboards.
• Comfortable and supportive built-in wrist rest.
• Number pad is separate which get the mouse closer for even better ergonomics.
• Calculator and screen lock shortcut keys on the number pad.
• Great price point.
CONS:
• Many of the shortcut functions are useless IMO.
• No volume shortcuts (only mute).
• No play/pause shortcuts.
A reasonably priced ergo keyboard with the TILT LEGS IN THE FRONT as they should be!
My only gripe (and the reason it’s “almost” perfect) is the “multimedia” keys are largely taken up for copy/pasting (cut, copy, paste, select-all). There’s no play/pause OR EVEN VOLUME, only mute. Copy/paste functions are easy to do one-handed and I don’t even need to leave the home position. Even if it just had volume shortcuts it’d be perfect for me.
This is the reason I docked it one star. I find it a glaring oversight. If this wasn’t otherwise a FANTASTIC keyboard the lack of volume keys would be a non-starter and it would be already returned.

Love this set up…its great having the number pad separate also
Peggy Colucci –
Would purchase again! It’s compact enough to travel and size able enough to use everyday at work! Super comfortable, battery lasts forever (I do turn both pieces off when I leave for the day), and set up was just plug and play!

I love this ProtoArc split wireless keyboard!
Micro-switches are overrated. They are! The entire PCMR has been led to believe that the only keyboard worth a darn is one that has micro-switches and I’m here to tell you that’s simply not true. Yes, high performance keyboards for gaming and specialty use see a huge benefit from this technology. But can you get excellent keyboards without? You bet you can – and you’ve found one right here.
Everything about this keyboard screams premium. Plastics are all great quality and beautifully uniform in texture and colour. The keyboard offers angle/tilt adjustments forward but not “up”, which frankly is probably better for your posture and overall wrist/CT health, anyway. Unfortunately, the numeric keypad doesn’t offer any kind of tilt adjustment. I found the integrated wrist rest to be one of the most comfortable I’ve ever used going back 40+ years (man, I wish the Commodore 64 and VIC 20 had keyboards like this back in the day!) The wrist rest is made with a textured PVC to keep you comfortable but still provide a sturdy base so you can type like a speed demon when you want to. The texture of the wrist rest feels like an expensive desk blotter. All the keys have a relatively short throw which makes speedy typing a breeze and the force required to actuate every key is a balance made in heaven. The ergonomic layout (utilizing a standard QWERTY layout for the main keyboard and split off editing and number pad keys) is just plain comfortable. Seriously, it is a joy to type on this keyboard.
Battery life is epic. It’s the kind of thing you do every few months, even with heavy usage. Both the numeric keypad and main keyboard have wide-cable accessible USB C charging ports so you can use your fancy charging cables or even attach magnetic charging dongles if you prefer to go that route. PD chargers are supported! Charging is indicated by bright red LEDs on both the keyboard and keypad located between the number keys and in the top right corner, respectively. I measured charging power draw at about 1 watt, which is absolutely tiny by any standard.
Having tested ProtoArc keyboards and mice for more than a year now I decided to replace my Logitech MX Mechanical keyboards with these EK series keyboards and MX Master mouse with a ProtoArc EM01NL. I find it much for comfortable and ergonomic for daily driving than my grossly-overpriced and online-only software-bloated Logitech gear. And the ProtoArc dongles and Bluetooth options just work – every time and all the time.
Highly recommended – ProtoArc keyboards are easily my favourite keyboards of all time!

A new keyboard is always something that you need to get used to. If you’ve only used a regular PC desktop keyboard before, you will definitely need a bit of time to get acquainted with this. It’s much more compact, and the numeric keypad is unattached from the main part. This is good if your workspace is limited, and obviously also if you don’t need to type numbers too regularly. In some way, it reminds me of the keyboards we had back in the early days of home computing, when the keyboard was part of the computer, on the Commodore 64 or the Atari 800. (Yes, I’m that old). There were no numeric keypads then.
The ergonomic design is also something that you need to get used to, as it’s a bit disorienting when you first try it. But after a few days, it feels very natural. It’s a bit disappointing that the keyboard doesn’t use Bluetooth, therefore using a USB port for the 2.4 GHz dongle, but still preferable to having an old fashion wired keyboard, of course. The battery seems to last a long time, and the fact that the keyboard power shuts off after a short time of inactivity definitely helps in that matter. I’m not constantly typing stuff, so I find myself often waking the keyboard up. There are switches to turn off the keyboard and the numeric pad, but there will probably be no need to use them, with the auto power off. I never flip the switch on my battery operated wireless mouse, and it still lasts a long time, so I’m sure I’ll be fine with the keyboard too. There’s a USB-C cable included to charge the keyboard, but just one, so unless you don’t have any other USB-C cables in the house, you won’t be able to charge both the keyboard and the numeric pad at the same time. But I’d be very surprised if both ran low on power at the same time, anyway.
The key travel feels very nice, not as much as a regular desktop keyboard, but better than your typical laptop one. So a very satisfying product to use, overall. It just needs a little getting used to, and you’ll be in business.

Essentially what the title says. I want to love this keyboard but they made the palm rest I have to find some sort of product to add some cushion.
*Update*
I added 3 layers of moleskin tape I had where my palms touch and it helped, it doesn’t hurt my wrist and palm within a few minutes of using it but I’m still getting strange strains throughout the tendons of my fingers and wrist. I think its got a poor ergonomic shape even though it looks just fine!

I like the split keys for ergonomics, but I have a narrow area and no real need for the extended calculator keys, so this is perfect for me.
You do need to remember to turn the keyboard off if you want the battery to last.
Pretty seamless from the box.

I purchased this keyboard along with another to help with my CPS. Overall the keyboard was very well made and sturdy. The keys were easily to get accustomedto.The separate number pad is great if you are a lefty and like to compute with your left hand. It has the 3 connectivity modes and once you got used to the set up was easy to operate.
The palm rest was too low/not cushioned enough for my needs. Also both units had/have to be charged which is a huge downside as I pretty much key PO at least 8 hours a day. Due to the fact I’m right handed the separate number pad didn’t really help me – it just took up more space on my desk and cause additional wrist strain when I had to move farther .
I would recommend this unit if you are looking for a more ergonomic desk option but do not already have carpal tunnel. (LISTEN UP – protect your wrist now because having this blows!!). I would also recommend if you do not do a lot of number work or if you are left handed. Great product – great company just not for me and my needs.

PROTOARC exudes quality in everything of theirs I’ve had the delight to try, and this keyboard + numpad combo really isn’t any different. It’s extremely well-built, wide and expansive. I appreciate that it’s wide since that does actually give some leniency to those of us who are larger – my prior keyboard was a very narrow mechanical, so it’s a nice change of pace to have something that aligns closer with the shoulders for proper ergo typing.
Feels good, the keys aren’t too muddy (note: not a mechanical keyboard) and while it’s going to take me a while to get over the learning curve of the extra space between the keys (not relative to an ergo, I just don’t usually have an ergo), I can foresee this being much more pleasant to use given my existing tendon issues. It doesn’t take them too much to flare up, and as a work from home tech, that’s no bueno.
Otherwise, what I really appreciate is that you have that nice, big, detached numpad that can be set on either side of the keyboard. I think that may even be the better of the items for my needs, since it allows me to get a proper numpad without blocking out my mousing area.
Anyway, another winner from PROTOARC at compelling pricing for a high-end ergo keyboard. I’d endorse it, my wrists aren’t hurting at the end of typing this, so that’s definitely worth its own vote.

the layout is great! the key bottom out nicely! the arrow keys are big and not anti human! small profile so I dont need to reach all the way to my mouse!
BUT why the wrist pad has to be hard?!?! I got a big hand and it hurt my palm so much, i have to put a small wrist pad on the left to ease the pain… not asking to make the wrist pad bigger, but just a bit softer please.
Still a great product, on the boarderline returning it, but still thinking about it

I love this small keyboard that’s actually not that much smaller in layout than my old big MS ergonomic KB, except that the detached numeric keypad really does make it much, much smaller. I like it so much that I bought 2 more with included mouse. I think that I remember that someone nicked this KB for not having a volume up/down. My Windows task bar has a “speakers” icon to click that can then be adjusted with the up/down arrow keys, so not a nick in my situation.
Inga Turner –
This keyboard is amazing!! Especially for lefties like me, the separate number pad is a lifesaver. And with it separate, if you have a small work space, you can put it in a drawer easily, even a shallow one.
It’s very comfortable. The keys are quiet, soft touch, and not too touchy or hard-strike. This is really the Goldilocks of keyboards.
If all you’ve used before is a straight keyboard this will take getting used to, but that’s just the nature of the beast; ergos take getting used to. But absolutely, if you’re looking for an ergo, and especially if you’re left handed, buy this one!

First impression: The packaging was nice, and the keyboard seems pretty sturdy. Both the keyboard and the numeric keypad sit very solidly, with no flex, rock, or movement.
I really love that the keypad is full sized, with a proper T arrow key arrangement, and the traditional/horizontal layout for Ins/Home/PgUp//Del/End/PgDn. The T-arrow keys are duplicated on the bottom right of the main keyboard as well, with fn-key alternates for Home/PgUp/PgDn/End.
The keyboard spacing is full-sized. I’ve used an ergonomic keyboard for years, and it took very very little effort to move to this keyboard. The keys themselves feel nice. There is much more key travel than on my Dell XPS laptop. The wrist-rest feels perfect when you’re using the front support legs.
As a programmer, I wish it had a separate rows for FN keys (which I need all the time), and all the newer navigation/shortcut keys. There is a FN-lock, so I can leave the FN keys active all the time, but that means I’ll really never use the other shortcuts. For me, the Fn button between the left CTRL and WINDOWS keys is just an annoying extra key that alters the spacing down there.
I do wonder about a few of the design choices…
Like, why does this keyboard use 2.4Ghz with a radio dongle instead of Bluetooth? That seems like a poor choice these days, especially when modern PCs and laptops all support Bluetooth, and laptops especially tend to have a dearth of USB ports.
The main keyboard has little legs that let you raise the front edge, but the numeric keypad does not, and having them at different angles is just wrong. This numeric keypad would be improved if it could be raised to match.
The physical power switch for the numeric keypad is conveniently located on the top edge, but the power switch for the keyboard is under the center bottom. Why??? I do like that they keyboard and numeric keypad both go into auto-standby after 10 minutes of non-use, and the manual says the batteries should last for around 20 days with 9 hrs/day use, so maybe I’ll just never need to use that inconveniently placed keyboard power switch?
The keyboard and numeric keypad are charged separately, but it came with a single charging cord. Sure, the batteries will probably last differing amounts of time for each, but I don’t want to be charging each alternately when it runs out – when it’s time to charge either, I want to do both at the same time and be done with it.
I’ve had a few disturbing communication issues with the keyboard – every once in a while, it will miss a keystroke, or worse, decide to repeat a key continuously until I press another. This caused a moment of panic one day when it was the backspace key that decided to repeat forever.
