Q & As

Rated 4.3 out of 5 by 3 reviewers.
Rated 4 out of 5 by Does what it says on the tin! I have a mini desktop which I use as a media centre to stream live TV and videos, so I didn't want a separate keyboard and mouse. The K400 was the ideal solution, though for me it had two minor flaws, hence only 4 stars. 1. I couldn't connect the wireless USB dongle directly to the PC as there was some interference. I had to use the USB extension cable supplied so that the dongle was away from the PC. 2. When I typed on the keys in the centre of the keyboard, the keyboard flexed a little. Other than that I am very happy with the K400. 29 March 2015
Rated 4 out of 5 by Small but packed with everything you need Bought this to access my samsung smart TV.mouse and all the buttons you need for quick internet access,don't sit too far away from the TV though. 02 April 2014
Rated 5 out of 5 by Need and tidy, mouse free tv browsing Purchased to connect to laptop and browse the web, engage in facebook and email correspondence from the comfort of my sofa. On opening and connection via the USB receiver, it worked 1st time no problem. The layout is a bit QWERTY if a bit qwerky as numeric pads aren't available but quite intuitive when using ESC key to operate screen changes from full screen selection. Keys are sufficiently responsive and well spaced to avoid spelling or missed text. Page Up / Down is possible by keys or two finger operation of the touch pad (mouse). Also pinch operation works to zoom / shrink image or maps. Certainly would recommend - it's a solid enough piece of kit, so see no reason to spend more. 13 February 2014
