I have been using this keyboard for work and personal use for 2 days and am loving it so far. It's perfect for my needs and here's why:1. It has all the functions I need and then some2. It's just the right size. I was using a separate keyboard for my personal pc than for my work laptop and the other keyboard is much larger, not leaving much room for my mousepad in the desk tray.3. It connects seamlessly to both, my laptop and desktop so I don't even have to use the other keyboard now! I wasn't looking for that but is a HUGE plus now that I have it setup. You can save 3 connected devices and switch between them using F1, F2, and F3. This was a huge help since I use the same monitor for both devices (I bought an hdmi splitter for that) but would have to use 2 different keyboard/mouse each time I switched. Now I only use 2 different mouses (mice?) which I'll probably upgrade as well.4. The keys have good response without being noisy. You can hear them, which I prefer, and feel the feedback, also preferred, but you don't have to press hard and don't get the loud click-clack of old school keyboards.5. It's comfortable to use, at least for me. The palm rest cushion is soft but seems like it will hold up for a long time. The major keys are reachable without lifting my palm and there was minimal adjustment from my much larger keyboard.6. Very easy setup (I use Windows...can't speak to Mac, Google OS, etc.). As soon as I turned on the keyboard, it paired with my laptop. I had to do absolutely nothing for setup (see note below).The ONLY very small con I have is that it doesn't tell you anywhere in the packaged instructions that you can pair multiple devices. I knew this from another reviewer. Even then, I had to search how to do it, because it's not obvious on the Logitech website. Once I figured it out, it was very easy to do (have your laptop/pc/whatever search for bluetooth devices and hold down the button F1/2/3 button that you want to assign to that device. The device will then discover the keyboard and you're good to go).Other Notes: I would recommend this keyboard to anyone. It's pricier than other keyboards I've bought but I didn't add a con for that because I believe it's definitely worth it. You can change how the function keys work using their application and even setup "smart actions" which will do a bunch of stuff like opening your favorite apps and a bunch of other stuff. All of this stuff is configurable too, although, I haven't tried to use it yet. I just needed a keyboard so I didn't have to use my laptop keyboard but got many features I didn't even know I needed! Get this keyboard!
