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

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)

I really like this keyboard! I bought it because I was in a bind and needed an ergo-keyboard that would get to me quickly...Man, this is a comfortable keyboard to type on. I really like that we have the option to use a 10-key but it's not attached, so I don't have to deal with a HUGE keyboard on my desk. That might be my favorite part.It's been really easy to get used to as well. I'm, seriously, only 8 hours in to using this (I got it last night and started using it this morning) and I'm almost completely used to this design and the key travel. All of it!

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.

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!

Gave it one star for minimalistic. A second star for ergonomics. A third star for wireless working flawlessly. I have been using this for almost a month and it has its flaws. 1. Some keys like the N, F, D (there are others) tend to double register the key press and I have found myself going back a lot correct this issue. It’s annoying. On that same note, there are also times that keys pressed don’t even register and I have to go back to correct that. That is also annoying and creates unnecessary work and consumes valuable seconds when typing. It can also just be my keyboard that’s faulty. Nevertheless, everything else I love about it. It’s minimalistic, ergonomic, love having the number keypad detached, love the sound of the keys when pressed. And it’s worth the money paid counting that the faults are isolated to my keyboard. One recommendation, try a greater angle for the ergonomic portion of it as this angle is almost flat.

Been using this for a few months now and it works great. Battery life is excellent. I didn't use the separate number keypad because I didn't need it. The ergonomic shape isn't as pronounced as a full sized keyboard but it's enough to alleviate the wrist pain I get when using the laptop's keyboard. Easily packs into my laptop bag.

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!
