This is my 5th purchase of a phone on Swappa. Remarkably, I have been satisfied with all of my purchases. I feel Swappa does an excellent job of monitoring its listings and ensuring that Sellers adhere to the terms of their marketplace. That's why I have, and will likely continue to, purchase phones on Swappa's marketplace. Plus, I believe that I have saved hundreds of dollars over traditional retail outlets and auction sites. I consider myself to be a very satisfied customer.
