I've always stuck to name brand controllers until yesterday when I saw that the Interact PowerPad controllers for Xbox were only $20 (thats half the price of the MS ones). They looked exactly the same, so I picked up a pair to try at home. What a mistake! These controllers are terrible. You have to push the buttons really hard to get a response, and about every 5 or 10 minutes while playing Halo you get the "please reconnect controller" message on screen, even though the controllers are plugged in. I looked around on the internet last night and lots of people are having the same problems. Just wanted to warn everybody not to get the Interact controllers! If you don't want to spend the $40 for a new MS controller, I read that the Mad Catz controllers are really good. I'm gonna take the Interacts back and get some MS ones!
