Excellent keyboard. More expensive than standard keyboard but great quality and portable.


Works to specification - allgood


good product does everything it says


I really like this keyboard, its light weight but sturdy so it is perfect for working for home or evening while I am away on business travel.
It has all the keys you need and more, great keyboard.




I first used one of these keyboards (together with a roller mouse) at work as it was recommended by Access to Work. I found it helped reduce my pain triggers considerably.

I ordered a keyboard for home use so that I could plug it into my laptop (quick is too heavy for me to have it on my lap). The lightness of the keyboard means that I can type much more comfortably than before. I would recommend it to help posture and reduce pain arising from various medical conditions. In the workplace, I would recommend using this keyboard with a roller mouse.


Not the highest quality plastics on the body, but the keys are great to use. That is what counts.


The keyboard does not have the normal configuration of keys. There is no "at" and it took ages to realise it would display that symbol using the normal key combination. You also have to use function and control and home to get to the beginning of the document.

Hi there, thank you for your comments . this doesn't sound right, Ill pop you a PM and we will see if we can figure this out for you , Kind regards


Key board is just right for me though I had in mind it was wireless
