I've gone through six different keyboards from different mfrs and couldn't find one I really liked until I bought this keyboard/mouse combo. One of the great things is it requires only one key to switch between devices, not a combination of keys. Key operation is soft, smooth, and quiet. Mouse switches between 3 devices, as well. Angle of keyboard has 3 options. Uses two AA batteries in keyboard, not needing cumbersome cable to recharge. I finally found a keyboard I love.

The setup was fairly easy with no reading or searching necessary. The mouse has many configurable features and buttons - more than any other mouse I have seen. In fact, there are too many buttons that tend to get in the way and sometimes interfere because functions are easily started by inadvertently pressing too hard in the wrong place on the mouse. There is also an annoying problem with sudden zoom-ins cuased by just moving the mouse, where the font becomes so small that a very large magnifying glass would be needed to see it.

This K850 keyboard is easy to use and quite portable, which is what I needed. Now that I've had it for about 10 months, the short legs that prop it up have broken off, and the rubber insert on one of the legs will not stayed glued on. Other than that, it's a great keyboard.

I liked the ergonomic style, the ease to switch connections to different devices and the customization additional buttons on the mouse. Both mouse and keyboard are comfortable to use. Both mouse and keyboard are relatively quiet but definitely not silent.

Works well. So far as good as more expensive models.

Small, easy to use, and light weight. Keys are not stiff like other keyboards as well.

I don't like the raised keyboard. And there's no volume control on it (or I haven't found it yet)

Love it

Keyboard and mouse works great! Easy set up. I love being able to switch typing between my desktop, laptop, and smart phone with a click of a button. The scrolling wheel on the mouse can switched to free scrolling (via physical button on mouse) to easily get to the bottom of a long doc or web page.

Love how I can switch between my Mac and windows devices without a problem!
