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) Review: Long battery life, good quality, good feel - 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! ## Features - Ergonomic Comfort Design: The wireless ergonomic keyboard features with curved and split keyset design, which helps to position your wrist and forearm in a more natural and relaxed posture. Scooped scissors-switch keys perfectly match the shape of your fingertips, offering quick response with every keystroke. Maximum comfort and productivity for all-day typing. - Hard Palm Rest: Curved, hard palm rest with leather surface offers extended typing comfort with more wrist support and durability. Kindly Note: This wrist rest is non-removable and it is not a soft cushioned one. - 2.4GHz Wireless Connection: Only compatible with Windows system, the ergonomic keyboard and number pad will both work as soon as you plug the USB receiver into the USB port of your computer, no additional drivers required, plug and play. Kindly Note: The ergonomic keyboard and number pad don't support Bluetooth connection and are not compatible with Mac OS.

Kindly Note: There are no adjustable tilt legs on the bottom of the number pad. - Personalize Your Setup: The separate numeric keypad provides greater flexibility for your workspace setup, greatly helps to improve your work productivity. - USB-C Charging: The ergonomic keyboard and number pad are built-in rechargeable lithium battery with 250 hours of standby time after 2 hours of full charge. - Warm Tips: The ergonomic keyboard and number pad are not backlit.

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.

Very happy with this purchase and would buy again! ### ⭐⭐⭐⭐ Great Value, Great Ergonomics *by M***Y on July 7, 2025* 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. ## Frequently Bought Together - ProtoArc Wireless Ergonomic Keyboard, EK04 2.4GHz Wireless Ergo Keyboard with Separate Numeric Keypad, Split Design, Wrist Rest, Rechargeable, for Desktop, PC, Laptop - ProtoArc Ergonomic Mouse, EM11 NL Bluetooth Rechargeable Wireless Vertical Mouse, 3 Multi-Device Connectivity for Computer/PC/Laptop, 2.4GHz Optical Mice for Windows, Mac OS, Black - Logitech Lift Vertical Ergonomic Mouse, Wireless, Bluetooth or Logi Bolt USB receiver, Quiet clicks, 4 buttons, compatible with Windows/macOS/iPadOS, Laptop, PC - Graphite --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/697163254-protoarc-wireless-ergonomic-keyboard-ek04-2-4ghz-usb-wireless-ergo](https://www.desertcart.gr/products/697163254-protoarc-wireless-ergonomic-keyboard-ek04-2-4ghz-usb-wireless-ergo) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-23*
