Just fine! Definitely worth the buy. I needed to replace two that were lost (I, of course, found them a couple weeks later), and these were excellent. Now I have four, and it's actually kind of awesome. They work just as good. I was a little hesitant, because of some reviews, and then the fact that non OEM controllers have a reputation for sticking and buttons being less nice and such - and these are absolutely fine. Some of my friends cannot tell the difference, and really don't care which controllers they get/use.
