Good value for money. Love that the phones are repurposed. They are great phones. I had to buy a better charger but that was no problem. The phone shop were amazed at the bargain I got for my Samsung. Keep up the good work Back Market!

I'm happy the phone condition is as described and everything seems to work well. I didn't expect it to be an American model and heard it can affect 5G connection it seems good so far though so hopefully doesn't pose any issues

I bought 2 of these, one for myself and one for my wife. I grabbed one randomly and had little trouble setting it up apart from some difficulty changing the temp from F to C. Someone else set up my wife's phone, and later she complained of all the unknown contacts on it. I had to do the factory reset you should have done.

Item was as per advertised. I didn't realise it was an ex AT&T phone so it has there apps on it that cannot be uninstalled. Regardless, the phone works, is in good condition, and is unlocked for use in Australia

Phone works great, other than the very small chip and hairline Crack that you can barely see when the screen is dark.

Now, that is what I call prompt service. I placed my order at 1:00PM on the 11th of June. Response notification advised delivery in up to four days (I presumed "business days". Today is the 13th of June. This morning I received a post-office notice advising there was a parcel t be picked up. Being one that usually has the dirty end of the stick, I struggled to see what the late delivery was (quelling and expectations). My order was undamaged and true to their word, it is hard to say that pre-loved items are not worth it. The next order will be to Back Market - without hesitation. Given time for packaging and posting, having it arrive two days later was FANTASTIC!!! Am I happy - you bet-ya. It is a bit hard to see why some others have had problems. My honest opinion is that Back Market are have set a very high bench-mark and have gone beyond. Thank you for the wonderful service.

Website stock is not up to date and they take days to notify you your choice is unavailable after purchase. They offer you another color, but not of equal value. lower. I cancelled and bought another model only to get a weak battery and a damaged screen. Fair condition on Reeblo is fairer and I doubt I will waste my time on back market again. Post was slow as well, compared to Reeblo. My first and last purchase from back market.
