Saving version of the white controller

I now had two of these controllers and both the Digikreuz is not working properly. Both only respond to relatively strong pressure, which incredibly annoying when navigating through menus. In addition, the complete Digipad can move, making it often comes up against the edge of the basin in which it is embedded - this creates a loud clunk.

Moreover, it was difficult to hear when one of the controllers within a short time a "spring" sound when the left analog stick has been moved forward. This he was no longer as supple as to move the other.

Even if the whole thing is quite difficult to explain, so it seems clear to me: Here Microsoft has saved. The original white controllers are high quality and durable. The spongy Digikreuz is already a joke, but it's often does not react an impertinence.
