Back Market sold me a refurbished iPhone 8. It looks new, and it arrived quickly. I imagine the battery life could be better, but it lasts all day, and I charge at night, so it never inconveniences me. An excellent purchase at an excellent price! And I helped keep one more little piece of electronics out of the waste stream:-)
Tip for consumers: Getting a locked phone is fine as long as you use the service it's locked to.
If you are lucky, you'll get a beautiful outfit that's the right size and properly sewn. If you are not lucky, either throw it out or give it away, because the company will not take responsibility or assist you in any way.
