I thought this was the answer to my prayers for numeric input on my laptop. Plus it is a mouse to save space. But to use it as a keypad it really sucks. Because the buttons are recessed into the frame of the "mouse" you can't get your thumb on the zero key. Plus it is harder than I thought to get used to it being the "mouse" AND the "keypad".I had to return the one I bought. Uhg.
