So here's my take - this company sources what you buy after you order it. The website displays as if they have stock but in reality they will order in whatever they can to fit what they have claimed to sell you.
The phones are often retired demos, or refurbished, and they do allude to this if you read very closely, however, there is no mention of what defects the devices might have.
In my case, I bought a retired demo (knowingly) in "excellent condition".
I bought a 128gb phone and was sent a 64gb in a dubiously sealed box, sealed by a sticker but not plastic, made to look new for some reason.
The phone had barely a mark on it but after some use I saw that there is a small defect in the screen, with a dead pixel and some discolouration around it, mainly only visible on full screen video.
This is my experience and hopefully may help to inform your decision.
