I bought this controller as an upgrade from my elite series 2, the fact that Microsoft hardware locks their controllers to 8ms response time is ridiculous. My R1 died day 1, but they repaired it with no issues (A+ there). What I don't like is that I paid for the sticks to be over tensioned and they are still way too loose. I got the shortest of the sticks and the aim rings are not thick enough to really help with the lack of tightness of the sticks. It's definitely an improvement over the elite 2 in a lot of ways, I just wish I could have tighter sticks and different paddle location choices.
