Someone had genuine interest in me as a customer. Broker and team went above and beyond to help me sell a token I wasn't confident I could handle myself. The best is their quality communication. A rare thing on the Internet today. They are quick, and the receipts are readily available. You do get what you pay for. Amazing.

I got one phone, and then decided that I wanted a different one so - I have ordered, returned, gotten refunded and ordered anew with these people. And I have to say it was all seamless. I love the goal of creating less electronica waste by reusing it, and the phone that I have now works great.
This was my second phone that I got from uptradeit. The phone was described accurate and arrived quickly. No issues at all.
