Wireless Ergonomic Keyboard, EK04 2.4GHz USB Wireless Ergo Keyboard with Separate Numeric Keypad, Split Design, Hard Wrist Rest, Rechargeable, for Windows PC/Laptop/Desktop

Works great, love that it’s rechargeable rather than using standard batteries. Been using it for two weeks (at least 100 hours spent), and it’s still running on my first charging session from when I opened it! Love the number pad separated so I can put my mouse where I need it. Key spacing was a little different from my last ergonomic keyboard, but I adjusted pretty easily and it’s not a big deal. Quality is good. Feeling on my palms/wrists is good. No issues at all with connectivity. Very happy with this purchase and would buy again!

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)

There are a lot of things to love about this keyboard and I'm extremely happy with my purchase after 2 weeks of using it non-stop. I purchased this keyboard as a replacement for an older Microsoft split keyboard. Pros: Setup was fast and easy and I was connected and using it in less than 1 minute. I'm using the USB dongle and my Thinkpad recognized the new hardware instantly. The height of the keyboard and the angle of the split feel just right. As a touch-typer I appreciate that almost every key I need (see comments below re: Home and End) is within easy reach and there is zero learning curve. The keys themselves have a scooped, low profile and are easy to press, with just the right amount of feedback. The leather wrist pad feels so much better against my skin than the weird fabric material found on many wrist rests. I don't notice it even after 8 hours of typing. The tiny indicator lights for function lock and caps lock are well placed and easy to see at a quick glance. Recharging is quick and easy with the usb c connection. Cons: There are only two things I would change that would make this the perfect keyboard. First, although the keys on this keyboard are low profile and have great action and feedback, they are comparatively loud. There is a lot of noise when I'm typing quickly and I miss being able to type quietly on conference calls. I find that I have to mute myself on meetings now whenever I'm taking notes because the sound of my typing is picked up by my microphone now. It's a bummer but not a deal breaker. Second, I'd like to see one more column of keys to the left of the main keyboard containing the Home, End, Insert and Scroll Lock buttons. Currently, those buttons can be found on the separate number keypad. But I use the Home and End keys all the time in everyday typing and I'm finding that I have to keep the number pad immediately next to the main keypad all the times so I can use them. It really defeats the purpose of having a separate number pad if I can't set it aside to save space until I need it. All in all this is a great keyboard and I'm pleased with the comfort and ease of use. It's a good value for the money and I would buy again.

An excellent keyboard. My old Logitech wore out and I didn't want to spend triple digits for a new one. I love everything about this one. Great size, keys feel nice. No connection issues. You couldn't ask for anything better.

Working out so far. Not nearly as ergonomic as I'd like. I would really like i the keyboard to be split into three pieces, out at least to have the split going down the middle of the letters. I do like that the numpad is separate, I can use it when I need it and set it aside. I would like if the letters were split as well. I also prefer wired, but I'm also not paying exorbitant amounts for a keyboard. No way in hell in paying $100+ for a keyboard. Anyways this is working out so far, the jets make some noise but it's not ridiculously loud. The actuating distance is a bit short, there are still mistyped characters from neighboring keys. This keyboard can take some force on the keys, so you don't have to be super light on the keys. I found using a little more force helped with accuracy.

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.

This ProtoArc keyboard was purchased so that I could include it with one of my laptops. I love ergonomic keyboards and as such, have some difficulty typing on standard keyboards. A full-size ergonomic keyboard, like the Logitech K860 this is replacing, is just too big to fit in most laptop bags. This, being a split design fixes that issue while still being comfortable to type on. ProtoArc has definitely filled the gap Logitech has left by overcharging for their products. This keyboard is light, quite easy to type on, and just looks good. My one and only complaint is that ProtoArc doesn't yet have the equivalent of Logitech's Unifying Receivers — you need a separate USB dongle for each device, or just pair the keyboard and mouse via Bluetooth and not worry.

I bought this to use for work and I absolutely love it! The noise level is very low and that’s the best part. I like that there is a separate number pad. It feels so comfortable on wrist. It is well worth the money, rechargeable, and there’s an off switch so you can save on battery power! It also auto shuts off when you don’t use it for a while as a means to save on battery power. When it shuts off there’s no lang between reconnecting when you hit a button! The set up was very easy and it looks good!
