Query: Seven Months

I have had three of these Logitech Wireless controllers now. They have all broken nearly seven months to the day I buy them.The problem is the same every time, the left analog stick breaks.My girlfriend got me my first one in December 2004 (Christmas). It lasted until about July 2005. I exchanged it at the store, and the new one lasted until maybe February 2006. I exchanged it again and now my third one has just bit the dust in September 2006.I am not really a heavy gamer. I play Madden and NCAA 2007 sparingly. I am very disappointed with this repeat problem.I also notice the "X" button sticking issue that others refer to here. I tried putting a little graphite in there to make it not stick. That seemed to work for a while.You really can't beat the convenience of wireless, and every other aspect of the controller is great except the durability.
