Anyone bought an O2 Refresh phone?

[Goose]

I've been toying with the idea of getting an S7e (although they're not in stock right now) for £320 but I dont really know a lot about where these phones come from. Are they all refurbs or repaired phones or just phones that were returned unwanted during the cooling off period? I've not been able to find a definite answer on the warranty of them either, is it just a 12 month job with O2 after which you wont get anything from them or Samsung?

Thanks

Customer returns AFAIK, Samsung phones come with 24 month warranty but i would imagine that will be from date of purchase originally.
