## Description

ProtoArc Ergonomic Foldable Keyboard, Split Folding Bluetooth Keyboard, Ultra Slim Travel Keyboard, Portable Bluetooth Keyboard for iPad, iPhone, Tablet, Laptop, PC

Review: Love this ergo keyboard! - Love this ergonomic keyboard! I got this since return to office resumed after covid and we had to hotel desks. I didn't want to carry my regular large ergonomic keyboard to and from everyday, this was the perfect compromise! Folds to a small size, very portable and lightweight. I just miss the number pad, and the lower function keys need to press func and shift to toggle to the 2nd option. I constantly lock my computer when trying to take a screenshot (the next button beside it.)
Review: Best keyboard! - This is the best keyboard i've used possibly ever? It folds nice and flat, so easy to set aside if I need my desk space. it's more comfortable to type as well. The only drawback would be if you have a PC and not a Mac (I have a mac). I haven't had any issues with bluetooth connectivity or battery dying either. The charge actually lasts a long time, and I don't even know how long because I charge it every couple of weeks to make sure it doesn't run out of charge while I'm using it.

### ⭐⭐⭐⭐⭐ Best keyboard!
*by M***Z on 12 February 2026*

This is the best keyboard i've used possibly ever? It folds nice and flat, so easy to set aside if I need my desk space. it's more comfortable to type as well. The only drawback would be if you have a PC and not a Mac (I have a mac). I haven't had any issues with bluetooth connectivity or battery dying either.

### ⭐⭐⭐⭐⭐ Best portable keyboard I've found so far (as of September 2024)
*by T***9 on 16 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
