It's funny but since I replied in this thread a couple of days ago the right bumper button my E2 replaced in September last year gave up.. I guess I'll go replace it again since it should be within warranty.. Good thing I anticipated it and have a brand new E2 I can use while this is being sorted out, lol.
Anyway, again, it's not just the E2, it's basically all controllers. It just hurts more with the E2 considering how expensive they are. From some breakdowns I've seen, most controllers, both Xbox and Playstation are for some reason using the same off the shelves parts for potentiometers (used for the sticks) and buttons, hence why they seem to have the same issues relative to type and time of usage, and Rnd.
