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.

Super quiet and slim keyboard
Color: Off White, Style: Battery Powered, Pattern Name: Keyboard
This keyboard is slim, stylish and super quiet! Very easy to set up and use right away without any problems. Seems very durable and I’m sure the battery life could be extended if I turned off the battery after using it but after a month of using it I have not had any issues. I bought the mouse that was recommended to go with it as well. Overall a great purchase.
