Excellent Product, Performs as Advertised
I needed a good portable keyboard for travel. After looking at various models of foldable keyboards, and based on the reviews, I chose this one. I’m glad I did. The keyboard pairs w/ three separate devices, so I have it paired w/ my iPhone, my iPad and my wife’s iPad. This ability to pair w/ multiple devices offers a wonderful degree of flexibility. One keyboard in the luggage and my wife and I are set. The keyboard appears to be very well made. It folds flat and very compactly. It is light, but the materials appear to be of good quality. I’m expecting good durability. Some reviewers complain that this keyboard is not really suitable for lap use. I disagree. I’m typing this review w/ the keyboard on my lap w/o difficulty. It has sufficient “rigidity” when open so that it doesn’t close up by itself, or even under moderate typing pressure. It would be nice if it had a mechanism that “locked” it open; but honesty, it’s fine as is. The key “travel” is very good and provides an excellent typing experience. My only complaint is that I wish it had illuminated keys. That feature would be very helpful, but even w/o that, this product deserves it’s 5 star rating.

I'd recommend this! Compact and useful when you need to type
This keyboard is surprisingly great! It folds up compactly, is very stable, and I like the keys. I haven't had any issue with responsiveness and have actually used this keyboard to play games on a SteamDeck. I've used this with a Galaxy Tab S9, Pixel 9 Pro, and SteamDeck and it works great on all of them. I would definitely recommend this keyboard.

A great product for writers on the go!
This is a fantastic product that feels really comfortable to type with. The size is spot on for me. It works perfectly with my phone and tablet, too. My only complaint, which is pretty minor but worth noting, is that there's no way to lock it into the open position (at least not that I noticed). Sometimes I want to type with something on my lap, and because if doesn't lock, you can't really do that. Fortunately, I have a lap table thing, but I don't always have that available. That's it, though. Like I said, pretty minor. This is a great product and a tremendous value, and definitely worth checking out of you're in the market for a highly functional, portable keyboard.

LOVE it so far!
LOVE it so far! Compact enough to slip in a bigger pocket, battery life seemingly lasts a very long time. I love the teal color and the leather-ish cover. Paired easily and battery charges quickly. Seems of good quality and materials. I'll update again if it craps out on me, but so far so good. Typing wasn't too cramped and I have thicker figures so the layout was good.

Great little keyboard!
I absolutely love this little keyboard - works really well, folds up nicely so you can just plop it in your bag. It is very easy to use - I type just as fast on it.

Great Keyboard, but Not Intuitive
3.5 ⭐ - It's solid! If a little finicky. This is a solid portable keyboard that I do enjoy! It's compact, connects quickly and easily and feels great to use! Great battery life, responds quickly and not a bad price for a FOLDABLE keyboard at that! However, the thing that kills me, and I still struggle with may be minut to others is the escape key. By default it just types which is fine, but 'fn + esc' will take you out of whatever app you are using as it's the home key, rather then esc like I anticipated. To esc you need to 'fn + shift + esc' which while not difficult did take some getting use to. Slows down work flow sometimes and I wish I could reprogram it better suit my needs. Solid keyboard! I enjoy using it despite my grievance. Would recommend! Just takes a little getting used to.

Sturdy, High quality materials, comfortable to use, I love it!
My son who is a missionary in a remote place where he does not have access to a computer and only uses a smartphone, wanted a bluetooth keyboard that he could use to type emails and other things like that. I searched through so many descriptions of different keyboards and finally settled on this one. Before sending it to him directly though, I got one for myself to see if it would be a good fit for him. Oh, my gosh! I am in love with it! It makes typing text messages, and other things that I usually struggle with on a phone, so much easier. It seems to be super high quality materials, and the engineering of how it folds and works is fantastic. Hats off to the developers. Pros: Smaller than my phone, it's easy to carry along. The keys are weighted to feel like keys on a regular keyboard. Pairs easily. Types great in all the applications I've tried it with, ie, Word, Notepad, 365, texting, emails. The little phone stand is adjustable and sits firmly on a flat surface, holding the phone at any angle I need. Cons: The keyboard is a little smaller, about 1.5", than a full-sized keyboard, but I play the piano, so I use the same techniques of curved finger positions and it doesn't bother me at all. My husband, who has a tremor, can't use it though. It's too small for him. Also, I think I will have to be careful with the phone stand. It may be a bit more fragile than the keyboard, but I still love it. Also, I do wish the on/off switch had an automatic off for if I forget to turn it off, but that's so insignificant that I still rate it 5 stars. If it continues to work well, this rating will stand. If it fails in the next year, I'll change my review.

Great little portable keyboard!
I have been using this for a little while now and pair it with my tablet on the road. It's portability is great. The battery life has surprised me and charges quickly. Even though the keys are close together, I find they are very responsive and the build quality is excellent. Once folded out it is very stable on a a flat surface. Works perfectly for my needs!
