This wireless keyboard and mouse are designed to encourage good hand and wrist posture. The Advanced Encryption Standard keyboard has a split dome shape to fit the curve of your hands, and the mouse's raised design allows you to keep your wrist in a more comfortable, natural position.
For an ergo keyboard, it's very comfortable to use. My only complaint is with the placements of some of the keys. For example, the delete key is very close to the enter key and if you aren't careful, you end up hitting the delete key by mistake. Also, because of the split in the keyboard, the F-keys are slightly out of position and more difficult to reach. Love the mouse and the separate number pad.
