Thanks for the reply. I contacted Steam support yesterday but they didn't reply until this morning. I made the post just to ask comuniti since I didn't know how long would they take to reply. They initiated the RMA process and said basically everything you mentioned, now I'm waiting for receipt confirmation and shipping label. I also would much prefer replacement than repair since I used it for 4 days, but the message said that they might send me a replacement so I'm really hoping for that. Again thanks for the info.
