Since I've only been working with this model for a short while, I haven't noticed any problems with it just yet. However, according to the observations of the elderly relatives who participated in the initial revision, after two years one of two things will take place: either the sticks will begin to wander or the buttons will become stuck. But in these kinds of situations, I found that giving the gamepad a thorough inspection and cleaning helped me, even though the analog sticks were still not functioning flawlessly after this.
