it was my first time too, and yes you do get to keep them until the new ones arrive
there's video's on youtube about it; basically you just create a ticket, say your controllers are drifting horribly and you're sad/disappointed, they will reply asking you to try some retarded shit, you reply that they didn't work, they will send you a mail + reply with RMA instructions and send you a new pair, you put old ones in a box + print their return label and go give the box to a store that works with their courier
