Logitech K380 Multi-Device Bluetooth Keyboard – Windows, Mac, Chrome OS, Android, iPad, iPhone, Apple TV Compatible – with FLOW Cross-Computer Control & Easy-Switch up to 3 Devices – Blue

I don't have enough good things to say about this keyboard. I have been using it nearly every weekend for five hour stretches at a time for the last three months. I've paired it with my tablet. I didn't want to get a keyboard that needed to be attached to the tablet, because I didn't want my knuckles hitting the screen. I also find attachable keyboards seriously lacking in features that this keyboard has. While still light and portable, the Logitech K380 has shortcut buttons that let me navigate between windows, go to my home screen, and control volume. It also allows me to switch between multiple devices in a matter of seconds. The fact that it doesn't have to attach to my tablet means that I can place this keyboard on a pullout surface of a desk, on top of a table, or even on my lap. I often pick up my tablet or move it forward and backward at different distances. Overall, it is much more ergonomic to have choices on where to place the keyboard. Most of all, I am enjoying the feel of the keys. Though it might not seem like it, the buttons take up the least amount of space needed, while still preserving much of the clicky feel of a regular mechanical keyboard. If you are a fast typist, this keyboard will not hinder you. I have even used it for a transcription gig. I knew that I would need something comfortable for long stretches of work, otherwise I wouldn't want to do the work in the first place, and this model checked every box. Looked good, felt good, light, portable, with features I wanted, and affordable.

As someone that is particular about the keyboards he will use, this one provides a great experience. For me the most important aspects are the general shape of the keyboard and the feeling when pressing a key. I type without looking, so I like when I can feel that the key has been pressed, and I also like the spacing to be just right so that I don't hit the wrong keys.For reference, I also use a Logitech K120 and a Unicomp Spacesaver M. The Logitech K380 is as comfortable to use for me as those two and I don't find myself wishing I had a decent keyboard, differently from when I use my laptop's own keyboard. The circle shape of the keys looks weird at first, but I find them natural to use and even comfortable.On the topic of connectivity, I enjoy having three different connections accessible with the press of a button. I have already set one for a tablet and the other one for my main computer, I might set the third one for my smartphone. Configuration itself isn't hard, but depends mostly on the device you are connecting to than on the keyboard. For me in both cases I had to activate the keyboard, set it to broadcast a bluetooth beacon by pressing the corresponding button (F1 to F3), activate it on my device, which would then show a pin for me to type on the keyboard. After that the keyboard was ready to use, but I did change the keyboard configuration on the Android for something that fits my tastes better. This part is more of a personal matter.All in all, it works well and I'm happy with it.

I am typing on the Logitech K380 that I just received.About me: I am old-school. I learned to type on a typewriter and I can do >60 wpm with a good keyboard. I yearn for the original IBM PC keyboard with its wonderful pitch, build, and feel. I still swear by a Lenovo ThinkPad for my laptop.About my needs: I would like to type more things on my tablet (and maybe phone) such as this review. Thumbs and swype/glyde get me only so far. Voice dictation doesn't do it either. I can tell right away that "a" keyboard is the right tool for me.About this product, the Logitech K380 Bluetooth keyboard:For the price (<$30) I can afford to break it or lose it. It paired easily with my 2015 Fire 7" and iOS 10.2 iPhone SE. On both devices there is no lag at all. The key spacing is a bit tight, probably no worse than my old netbook, but nowhere near ThinkPad good. See picture for comparison with actual ThinkPad. The Logitech is about 1cm narrower from the 'Q' to the 'P'.The key travel is as good as a mediocre laptop, and definitely worth my price. I can feel my fingers cramping up already, after about 100 words, so it's not for heavy-duty typing. Some reviewers commented on the round keycaps, but I adapted to them right away--except for the right-hand shift key where the rounding makes a difference for me. Standard combinations like Ctrl+x for cut and Ctrl+v for paste are supported.The build seems more than good enough for the price. I will try to write an update.When typing I do have to be careful because the function keys map to their specific tablet functions like homescreen (F4), switch app (F5), and tablet/phone/Android backscreen (F7). In typing this review, I overshot the '7' key and hit F7, which sent me to the page prior to the "Write your review here" page... and so I lost all my work.There aren't clear instructions for how to use the various keys, so you have to be icon-literate. The F4 key has a pentagon (home), F5 has the stacked rectangles that mean "switch app" and F7 has the left-to-right swoop that means "backscreen" as on older Android devices (sorry iOS people). The volume and playback icons on F8-F12 and INS are pretty universal. There doesn't seem to be an equivalent for the ctrl+<right> combination to skip words that I use a lot. But fn+<tab> will pull a screenshot (that's much easier than Android's <power>+<volume down>).I recommend this device.UPDATE: glitches with iPad Air 1--single quote does not work. Shift generates double quote and single quote works on other devices.
