Query: Jumpy mouse and too small keypad

I have used other wireless keypads and mice before, but these are not up to the quality and usability of prior purchases. The keypad is smaller than a normal keypad and the key placement of the primary function keys is unusual for someone who normally can 10-key by touch. For some reason the mouse is really "jumpy". when I plug it in it jumps all around the page, but will eventually settle down after it gets "tapped" a few times. All in all, I think I got what I paid for as this was much cheaper than others.
