Input: I have owned this keyboard for two years so it is worth saying that I'm impressed. The keys are all flat except the top row of buttons which act as programmable functions if you press down on them. It's very nice not having a split layout. It has many features over competing keyboards such as: a volume control to get rid of unwanted noise from your computer, an audio input so you're ready to listen to music via speakers or headphones, and even a media card reader.
Output:
Good Review
