Gazelle works just as they say. I went to the website, got a dollar amount offer for my device and clear instructions on how to wipe it, and received their box in the mail in 2 or 3 days. I popped my old phone in the mail the next day and received an email with an amazon gift card shortly afterward. The whole thing from start to finish took 8 days. Ive used Gazelle two or three times and its been this way every time - easy money! I see some reviews where people have complained that Gazelle didnt honor the quote or claimed the device condition wasnt as the customer promised, but Ive never had that happen and plan to keep using Gazelle in the future.
