Review: I recommend it - Works nice, compact and light, battery lasts well. It is very flexible, and this may be helpful or harmful depending on you needs.
Review: Best portable keyboard I've found so far (as of September 2024) - I like that the size and design makes it feel more like a folding full-sized keyboard. I was able to pick up the ergo layout quite quickly and it feels great when I type on it. The keys themselves feel nice and the travel they have is decent. Key actuation is accurate, soft and feel like Logi's MX mini keyboard. It's also much quieter than other folding keyboards because it has a "leather" housing rather than the folding mechanisms and complex hinges that others use. I've owned several portable keyboards and I can never type fast on them because their smaller size doesn't match my muscle memory. Using those keyboards for an extended period of time was something I would avoid. The design of this keyboard mitigates that issue. It did take me a few minutes to adjust to the ergo layout but it feels natural. My only concern lies with the "leather" hinge that could potentially wear over time. I wish ProtoArc would have included a case for this keyboard since that would help protect the hinge when on the go. Luckily, one of the cases I had for another folding keyboard fit. I intend to throw this into my daily use backpack. I will report back if I notice any issues, degradation, or wear that I find concerning. I've been using this with my Steam Deck and my iPad and it's worked extremely well. Overall really happy with this purchase so far. Pros: - Turns on immediately after you open it; remembers last device (1-3) used - Keys don't feel cheap like other folding keyboards - Less noise overall especially while typing; keys don't "chatter" like on other keyboards - No issues with keys not activating when pressed with reasonable force - No complex hinges or moving parts Cons: - No case was included - "leather" hinge could wear down with age

### ⭐⭐⭐⭐ Excellent travel keyboard, but the function keys can be tricky
*by D***T on August 19, 2026*

I love this keyboard. It's lightweight, folds up nicely for travel, and the ergonomic V shape is very comfortable to type on. I was having wrist pain with a traditional keyboard, and this setup puts my hands in a much more comfortable position. I noticed a significant improvement in my wrist while using it. My one issue is with the function keys. There isn't a traditional row of dedicated F1 through F12 keys across the top. Instead, the function keys share keys with numbers and other commands, so accessing something like F7 requires pressing a combination of keys. Normally that wouldn't bother me much, but I was using this keyboard while studying for an exam and needed certain function key combinations. I ran into a situation where I needed Shift+F7, but activating F7 already required multiple keys. At that point it became more hassle than I wanted to deal with. I ended up buying another keyboard with traditional function keys specifically for studying. That doesn't mean I'm giving this one up, though. I still love it for traveling. It's comfortable, lightweight, compact, and easy to pack. If you rarely use function keys, you may never care about this limitation. If you regularly use F key combinations for work, studying, or certain software, it's something I'd consider before buying.
