Query: Not For Serious Gamer Use

I found this controller to be good for only about 20 minutes. After that, the buttons and analog sticks sticks start to have a reaction time that usually gets you killed or makes you lose a race. I did buy it refurbished though, I'm not sure that that would have made a difference. I will definetly never buy this controller again or anything else by Longitech.
