Takes time to get used to
Should get the corresponding mouse pad.
I use it for work, at least 8 hours a day.
It is quite comfortable and helps with the tension in your wrists. I find it helps to have the desk and chair at the right height, and also to have the keyboard slightly elevated.
At first I was annoyed by the hard piece from between the pads, but it actually forces you to correct the position of your hand while you type. If you don't want to keep your wrists so close together, it is also easy to use the single round pad at the right with your left sitting opposite.
I feel I am definitely missing the corresponding mouse pad. If you can, get them both at the same time.
