This keyboard is a decent size at almost 44*13cm. The keys are well spaced out and in operation it's not too dissimilar to an Apple keyboard. The key strokes are responsive and sure. They are relatively flat at perhaps a mm or 2 in height. What I thought was particularly good was the inclusion of a flat indented cover which fits perfectly over the keyboard to keep in clean and you can actually type with it on also although your fingers tend to grip a little on the keys when using the cover. Considering, it's only to keep the keyboard clean, being able to type with it on at all I consider a bonus and a nice touch.
The included mouse is quite flat, again similar to Apple's and includes a dpi button as well as a scroll wheel. Both items are relatively quiet in operation with the mouse being the quieter of the two.
The included unifying receiver didn't actually work but i had a spare from another brand and I was able to pair both up to this with no issues.
At £30 this is remarkable value for money and whilst I haven't had it long enough to confirm battery life, the quoted battery life is great and I haven't had any issues so far. Both also switch off after a short period of time to prolong battery life and a quick click of either will prompt them quickly back into life.
I borrowed my friend's Logitech MX Keys keyboard prior to ordering this and when it arrived I was supper happy that I had made the right choice given the much cheaper price.
Highly recommended. Thanks.
