Virtually all controllers share similar technology and one of the features for most of the console manufacturers is that they will break the moment a piece of lint gets stuck between the stick and the sensor. Given how difficult it is to access the sensor in order to fix the issue, and also how open-air the design of these sticks are, I've always assumed that this is on purpose.

I've started using the Power A controllers with the back paddles on PC (or a Razer Wolverine when I was being fancy and wanted LEDs), and I'm much happier now. The only problem I've had with Power A's controllers is that the USB cable has a plastic housing that is a bit oddly shaped and thus it's nigh-impossible to find a replacement, so I'm still stuck with a scenario that I have to RMA a replacement from time to time because they won't sell the cord by itself.
