Got my sixth Xbox one yesterday...
1. Bought at launch, replaced with S and gave original to my Dad
2. S - Lives in our living room for family gaming
3. X - Got Christmas 2017, DVD drive began playing up conveniently 12 months later, once warranty passed. Repaired it, worked for a week before it completely failed again.
4. X - To replace 3. Wife wanted me to clear out a bunch of stuff so did a huge trade to CEX and got a White X on the 12 of Jan. It immediately was showing signs of the same problem as number 3, so after two weeks it went back to Cex last Saturday, who after checking it over issued me number 5.
5. X - Decided that I wasn't going to take a chance on this one, so got the best one from CEX I could in an immaculate box yesterday, then walked straight up to Game and traded it against a brand new one, paying the difference.
6. X - I have a new one... let's see.
