It's much like their more expensive model that comes with backlighting. I don't need the backlighting on this one because it's for the office so I'm never typing in the dark. I also like that it just uses regular batteries so between that and the lack of backlighting, the batter life is expected to be phenomenal. Clean looking keyboard and a pleasant typing experience.

Perfect Work Keyboard

Color: Graphite, Style: Battery Powered, Pattern Name: Keyboard, Color: Graphite, Style: Battery Powered, Pattern Name: Keyboard

This keyboard is perfect and exactly what I needed. I wanted a higher quality wireless keyboard for work and this one is that plus some. Keys are not too loud but also not silent. The keyboard itself is thin but not too thin and has weight to it. Also love the ability to connect to other computers with the press of a button. I have a PC for work and Mac for personal use, it switches fast and easy without fail. It’s a little more of an upfront cost compared to others available but it’s worth it truly. Plus the Logi brand itself has gained my trust as all of my other tools (headset, mouse, and webcam) are all Logi and have been excellent. If you’re on the fence due to the price, just purchase and know you’ll never have to buy another keyboard again.

Great keyboard for my mother.

Color: Off White, Style: Battery Powered, Pattern Name: Keyboard, Color: Off White, Style: Battery Powered, Pattern Name: Keyboard

I wanted to move my mother away from corded keyboards so I gave her my old mouse and this keyboard. Functions well with a Linux machine although you have to pair any mice with it on a Windows or Mac computer. It's quite responsive and connects well. A valuable purchase that has survived some falls now. Very durable as long as you're not purposely trying to break it.

Good quality keyboard

Color: Graphite, Style: Battery Powered, Pattern Name: Keyboard

The Logitech Slim K950 Wireless Keyboard works great as a replacement for my old Logitech USB keyboard, but it's not perfect: Pros: Logitech is a good brand that lasts a long time, very easy to connect via Bluetooth (ready to use in minutes) but also comes with a USB to connect manually; runs on two AAA batteries (have not had to replace yet in over a month); Slim profile with low-profile keys; no problems with the functions on the keyboard so far; it's a regular width keyboard with convenient number pad. Cons: It is a bit pricey compared to some other Bluetooth keyboards; the volume keys are above the backspace bar and sometimes I hit those instead of backspace; the main issue for me is that it is supposed to have keys that are "quiet typing" - I don't like "clicky" keyboards and this one still clicks if I am typing fast or pressing hard. Not as much as other non-silent keyboards, but enough that I notice. That said, I tried a couple different "silent" keyboards and they really were not that much different, so maybe it's just me! Overall this is a good keyboard and I would purchase Logitech again.

Amazing

This is a very good product. I have had mine about two years now and I will buy another one should this one start to wear down.
