Very easy to get used to quickly, simple and modest design, much less fatigue or pain

DBStevensDecember 16, 2025

It's a bit hard to write a review about an item that requires you to learn new habits, because the initial difficulty tempts a person to feel a bit of negativity. But I give this keyboard 5 stars because after you spend some time with it and learn those new habits, it lives up to its claims as an ERGONOMIC keyboard. I've used traditional keyboards since the mid 1980s and am very used to them. For much of that time it was professional and I sat at a typical desk. I paid attention to chair height, etc. and never consciously felt the ergonomics left anything to be desired, even though I half-consciously considered extended sessions with setups like that to cause upper body pain. But these days I spend less time at a computer and so I tend to use a keyboard in my lap while in an easy chair or curled up on my bed. At those times, a standard keyboard can end up causing noticeable discomfort, especially in my wrists, shoulders, and neck. So I've sort of half-heartedly tried some ergonomic keyboards and even when giving them a chance by using them for a few days, they all fell a bit short. In my opinion, many of the ones I've tried exaggerate the modifications such as the non-traditional angles or split orientation. Adjustable ones are better, but often the weird angles are a bit TOO weird. Although this keyboard isn't perfect, it's more modest and feels much more natural after just a couple of days of use. You can adjust the pitch of the angle with the legs on the back. And the design of the keys is simple - no extra keys to have to figure out. The placement is pretty traditional, which helps get used to it. I know that everyone is a bit different, so not everyone may adapt as well to this keyboard as I have. But the angle of the split keyboard is very comfortable for me, especially when sitting in a chair or in my bed. They touch of the keys is easy to get used to, and the layout is comfortable to me. I wouldn't exactly call it a "mini" keyboard because it's pretty much full-sized. But it's definitely a bit more compact than traditional keyboards and easier to manage. And of course, the wireless aspect is great! It's also very nice that this keyboard can be used easily with Macs or PCs and other devices without any extra effort. It's well-designed. And in the end, the most important thing is that longer sessions while using this keyboard don't result in nearly as much physical fatigue or pain as traditional keyboards. Read more

Excellent keyboard and a GREAT size, too!

MarilynDecember 3, 2025

Ordered this because I am a big fan of ProtoArc's products. I've used them for a while now and they have never disappointed me. Their customer service and warranty is top notch too. I have an ergonomic keyboard of theirs that I got a little over.a year ago and it's a GREAT keyboard - responsive (even for a membrane keyboard), comfortable, and efficient. But it has one thing that I am not a fond of...it's SO BIG. It takes up a lot of room on the desk...so much that I ultimately stopped using it and went back to a mechanical keyboard. I know some people don't like them because they are noisy, etc but you have to admit that they do one thing well - they are thick and chunky, but still have a small footprint. With that said, I was super excited to see that this has been redesigned to be smaller - and that has made a HUGE difference, at least for me. It's smaller footprint has enabled me to use a proper ergonomic keyboard again and it's a pleasure to use. Here's why: 1. Size! It's a normal size even with the wrist rest. Whoever designed this version of this keyboard...kudos! 2. It's super sturdy and stable. You have to TRY to make this malfunction or break, even if you are using it very heavily. I've only had one ProtoArc keyboard malfunction - and that was after a couple of years of daily use - and it was just one key that was sticky. They honored the warranty and sent me a new one, no questions asked. 3. It mimics the correct hand/arm position that is most ergonomically beneficially for your hands. So...it's comfortable even when you are typing for long periods of time. 4. It charges FAST, stays charged for a long time, and it give you reliable, steady performance. 5. It keeps up with even the faster typist with no latency or lagging. 6. It's a nice design and well built, so I feel this should last for a long time. 7. It's a great price, especially given the quality of it's build. 8. It's easy to connect via Bluetooth on both a Mac and PC. Overall, if you are looking for not a good ergonomic keyboard but a GREAT one...this one is a great deal all the way around. I highly recommend it!! Read more
