There is an obvious design flaw and the only reason I bought this extra controller was so that I still had two while they decided on repairing the other or replacing it

The reason they easily earn 2 stars is because they have a very consistent design flaw (that for some reason they never fixed as reviews poured out) that causes the clicking function of the touchpad to deteriorate, eventually losing 1 or all 4 sides of clicking capability

There are serious design flaws with it.

This has a MAJOR design flaw regarding the touch pad
