– XK04 Mini Foldable Bluetooth Keyboard with PU Leather Cover | 3 Bluetooth Channels, USB-C Rechargeable, Compatible with Windows, iOS, Android, Tablets and Smartphone

Properly good. Reasonable price with a £6 discount. Very clever design, feels sturdy, folds wonderfully, connects instantly. I’m so impressed! The only thing I would like to see added is a little fold down flap to raise the back edge slightly. As you can see I compared it to another brand bought on here but this one is so much better and more compact, the other is very springy to type on and feels cheap in comparison and will be returned.

Brilliant little keyboard. Fits in a jacket pocket and is slightly larger than an IPhone 13 or equivalent. In regard to use case, I use the XK01 as my remote desktop keyboard when away from home and it is arguably the best travel keyboard out there, however I was finding it was a bit too bulky to carry with me when I was out for the afternoon and I wanted to leave my laptop/ remote setup in situ. The new XK04 is a keyboard I can see as something that can fill this gap, as this is a perfect size to carry in a jacket pocket for when I'm working from a cafe with my phone as my main note taking device. Although I've only had this keyboard for a few hours, ProtoArc's XK04 is very similar in its overall appearance to a generic folding keyboard I've been using recently, but it appears to be more refined in design, use of materials, key travel and overall usability. My only minor criticism would be the size of the function row, as I think this could be smaller in future revisions to allow for the main keys to be slightly larger, but it's not a deal breaker. Overall this keyboard is much better than other offerings I've seen to date at this size/ form factor. Definitely recommend.

I ordered this to replace my Samsung Trio 500 keyboard which I mainly use with the tablet but occasionally use in my office setup. I wanted a small, foldable keyboard to use on the go as part of my editing flow as well as part of my office setup, and on paper this keyboard seemed to fit the bill. When the keyboard arrived, I was really impressed with the quality and feel of it. It folded to a really small size, ideal for travel and comes with a cover and a phone/tablet stand. Easy to charge and pairing to 3 devices was a doddle. The keys felt sturdy with good feedback for typing. The downside was it was just that little bit too small for me, especially using in an office setup. The other annoyance was the placement of the lower hinge which rubbed against my hand when typing. I think this would a good little keyboard for short term travel use but it didn't quite meet my needs. If it had been a little bit taller I think it would have been just right. As it was I returned it and moved to the ProtoArc XK01. I am only giving this a 4 star due to the hinge as it is still a lovely little keyboard.

Full disclosure: I returned this, but only because it didn't fit my specific needs. I think this is an excellent keyboard to take on travels or as a remote working tool. I can touch type and can do so easily on this. Some people complain about the hinge or something getting in the way of the thumb when hitting the space bar - I didn't notice this at all. I wouldn't choose this for a permanent desk setup, but for anything where portability is needed then this would be great. As I say, I returned this. Instead I chose the Doohoeek mini. The Doohoeek isn't as good for typing, though I can touch type on it, but i specifically wanted something ultra portable where portability was more important than typing. I only need it for messaging on my phone whilst on holiday, where I haven't taken a laptop or tablet. I hate writing anything bigger than a short sms on my phone screen. The Doohoeek also won by having no hinge (which I figured potentially, rightly or wrongly, was a point of weakness / future breakage) and by having a built in stand. A neat all in one solution - for my specific needs. Having said that, I would have no hesitation in recommending the ProtoArc if it fits your requirements.

I think it works extremely well, and folds to a relatively small and convenient size. The additional little stand for your phone is a nice touch. Unlike some other keyboards that fold down the middle, there is no increased gap between the keys to accommodate the hinge mechanism. This makes typing easier to learn as all the keys have equal gaps between them. Blue tooth pairing is easily set up and stored, for upto 3 devices. Typing is easy to do and the keys very responsive. It's not a full sized keyboard, so if you're a touch typist you'll need to make some adjustment. I found it easy to do so. One thing that would have been useful would have be a carry case or pouch.

Great little keyboard, comfortable to use. Very compact

This is a really-neat, well-designed little keyboard that's easy to love and would be perfect for very-occasional travel use. It's great value for money and seems well built. There are two problems, however. Firstly, the keyboard isn't angled, so that makes it unpleasant for typing. Secondly, there's a hinge (from the folding mechanism) bang in the middle of the bottom edge, right where your thumbs sit in the "home position". Now, if you're a "hunt and peck" typist, that won't be a problem - but for us touch-typists it's a major irritation, and the reason I ended up returning the keyboard. For me, Apple's brilliant "Magic Keyboard" doesn't take up much more volume or weight, so that's what I ended up buying. Windows users may need to find something else.

My Bluetooth Keyboard arrived on time 2 days ago. It feels well made & was very easy to pair with my iPhone, iPad Pro & Amazon Fire tablet. The keys have a nice positive action & click when pressed. I also like the handy little stand that comes in the pack, along with the charger. The stand works well with my iPhone & Amazon tablet. I won’t need to use it with the iPad as my iPad already has its own stand. I don’t agree with some reviews which say they hit their right thumb on the central hinge when pressing the space bar. I don’t know how they hit this hinge, my thumb naturally hits the centre of the space bar & nowhere near the hinge, so this is not an issue whatsoever. So far I am very happy with my purchase.
