I originally sent my iPhone 5s to Amazon. They rejected it because it was too scratched for them. I mean there was some wear, but it worked fine. After I received it back, I decided to send to Gazelle. I sent it in, marked the condition as Fair after my Amazon experience, only to be told that the phone was broken. When I sent the phone to Gazelle, it was in fine working condition. I'm sure it got damaged either on the way, because they make you send it in flimsy packaging, or someone working there fried it. I'll never use them again.
