Yeah, this is exactly how it was — I got it on a whim, one day I was like: I really want to play Halo 5! And I got a refurbished console with the game because the discount was good. Turned out fine — other than having a giant sticker on it claiming it's refurbished, I don't think it was different from a brand new one in any way. RRoD was a problem with original Xbox 360 batch, I don't think Xbox One ever had such issues, there was a problem with my unit emitting a high-pitched noise when updating at night time, as the console is in deep sleep mode even its fans are off so it's very noticeable. At first I thought that it might be a problem with my unit as it's refurbished, but turned out it's a common problem — since then they have either fixed it with an update or they have just stopped releasing patches that often and the problem became less prominent.
Other than that — no issues at all. I'm not such an avid gamer, but I have it for about 9 years, it got borrowed by my friends on several occasions, so it has seen some shit and still works — I doubt anything would happen to it at this point. In fact, I think buying used or refurbished is the safer route with modern hardware: if it didn't break down immediately, it means that it's very likely to do so after the warranty expires — and when you're buying used, even that didn't happen. And with refurbished units — people seem to be cautious about such things, but to me it means it did break down from the get-go, but original manufacturer has taken a second look at it and fixed it, if some parts in that revision turn out likely to be faulty, they usually also get replaced.
