As a Pixel fan for many years (going all the way back to the HTC days), I was excited to trade-up my Pixel 6 Pro to the newest model, having held-off all the way through the 7, 8, and 9 Series. I had been looking at a new 10a, but when I saw how little I could buy a 10 Pro XL for on Back Market, I jumped at the chance.
The 10 Pro XL I received does have a mid-size scratch on the screen, which you can both see and feel with your finger. I resolved the "touch" part of the issue by putting a glass screen protector over the screen, so that problem is gone. The visual issue is still there, but it's minor enough that I don't mind it very much - the phone was in fact listed as being in "fair" condition, but the truth is other than that one issue it looks completely brand-new, and considering how much I saved on the purchase I have nothing to complain about. However if you read Back Market's description of "fair" it would seem that a scratch that large would not classify as a "fair" condition device, so that part did come as an unwelcome surprise. But still, overall the phone looks and feels brand-new, and I'm absolutely happy with the price I paid for it.
My one negative about the experience was I was offered a generous trade-in value for my Pixel 6 Pro, which was reduced significantly after they inspected it. I'm a technologist myself, I'm very much aware of what condition that phone was in when I sent it to them, and my frank opinion is that they are being somewhat unethical in their valuation process, and may be offering inflated trade-in values they have no intention to keep , in order to close initial sales.
Thus far very satisfied with my purchase, which was my first time every buying from Back Market. However I will going forward have second thoughts about using them for trade-ins, I honestly believe they are being less than ethical as a firm in that area.
