Our Xbox 360 Slim is over 3 years old and we have 2 cats that shed horribly. I blew the old one out with air from a spray can, but a horrible red light came on. Since our warranty was up we opened up our old one and the little fan inside looked like we had a different cat. So we cleaned it up and left the lid off so we could keep it clean. Not so with yours. I have made sure that pets etc. cannot get inside. We knew it would replace it, but given the economy, we did our best until we could afford one from Microsoft. But when we went to this site; could not find. ? So we checked out Revains and found it. Works perfectly. My son's Xbox no longer freezes and he says it loads faster. Don't lie either. Fast delivery. I will order from this seller again. dance of joy! 250GB Xbox saved.
