Amazing product!! Super satisfied
This little keyboard is so cool and amazing!! The bluetooth function works very well, the space for your phone or Ipad is so helpful and one of my favorite things about the keyboard. The sound of the keys is very satisfying, the battery life is also top tier. Almost never dies on me, the charge lasts forever. The pink color is soooo much cuter in person and overalll such a nice addition as a writer/student.

Click clack, click clack
If you are looking for a more affordable typewriter keyboard, this is it. The keys are in the right place, not squished together or compacted, and they make the click-clack sound I was looking for. I love the round shape too. No, it doesn't sound exactly like a typewriter. I don't know if any of them do, but it is a nice sound. So far it has great battery life after a full charge. It was an easy connection via Bluetooth, and I haven't had to reconnect it since the first time. It is also comfortable to use. The knobs are a nice touch. I had trouble with the volume knob at first, so I tried Fn+turning and it worked. I only had to do that once and then it worked with just the knob. The light pink and off-white keys are a great combination. It is aesthetically pleasing to me. It is a good pink too, not one of those weird shades or pepto pink. I would call it a soft pink, or powder pink. I love this keyboard!

Half the keys don’t respond-Edited
I hoped a mechanical keyboard would help with my problems with dexterity but this was a disaster. I really wanted it to work out, it’s a great size and the right idea. But it just doesn’t work well. I may order another in case it was just a bad unit, but this one didn’t cut it.Update: the manufacturer contacted me and very nicely expressed concern. They offered information on resetting the keyboard or to send me a new one. Since my return is in transit, I can’t try the reset but I said I would be happy to try a new keyboard. Stay tuned!Update: Received the replacement keyboard today and charged it and tested it. I have to say, the performance is much improved. There still seems to be a little hesitation on the backspace key for some reason, but I can’t rule out that my relatively small hands are just not pressing it hard enough. The keyboard is cute and old fashioned looking and I like the clackety-clack. I like that the slot for devices is amply sized and it easily holds my table in landscape mode, although with my tablet in landscape, there isn’t enough room to include my phone in the slot as well. In portrait there’s plenty of room. It also holds the tablet at a good angle. The keyboard has little flip-down legs that you can use or not, and it changes the angle of the keyboard slightly which is a nice feature. I like that there are separate PageUp and PageDown keys. There is an ESC key. Interesting touch that the volume of the device can be controlled with a knob on the keyboard.This one came with a user booklet that I don’t that was not included with the first one I got. Manuals can be helpful. I checked Yunzii.com and the manuals for all of their keyboards are out there as well. The portion of the user booklet that explains the function key sequences and what they control needs a little work, Yunzii guys. Maybe it would work out better in a table.Overall, I’m glad I retested this because I do think it’s a fun keyboard to use if you’re looking for a mechanical keyboard. It’s cute, meets most of my needs, good price point so I changed my rating.

Buy Two in case they go out of business
Works perfectly for 3 devices. My desktop PC, my iPad Pro and my android phone. The bulky retro look and feel inspired me to type so rapidly. There’s no lag. The only problem is the thin gap for my iPad. You need a super thin case for your touchscreen device in order for it to fit. Not worth taking away a star though. So perfect 5.I’ve never heard of this brand before and it’s quite affordable. I hope they stay in business for a while but just in case, I bought 2 and left it in the box for later on when this one burns out.

Super clacky, but so aesthetically pleasing!
It completes my desk setup perfectly. I waited a week or so after using before writing a review to be sure I wasn't going to have any technical issues. Connects flawlessly every single time! It is very clacky (which is the purpose of thus kind of keyboard I would think), but it is so much so that I will not bringing this with me into the classroom, just keeping it for my desk at home! I love the volume control knob as well! All in all, it's a great keyboard, but not ideal for constant use. I notice my wrists tiring after a consistent amount of use just due to the depth of the keys etc. I'm still giving it 5 stars just due to how it looks and overall functionality. I would recommend it if you want cute and clacky!
