On 10-11-16 I went to DM Bros Phone World and purchased a Samsung S7 edge. These guys have excellent customer service. First off they cut my micro SIM card to fit into the nano SIM card slot, saving me time and money from going to an AT&T store. Another positive part of my experience was they threw in a case for free. I Will be shopping here again, as they assured me my product comes with a one year warranty even tho it's a used phone.
