    My phone arrived on time and in good condition. Now I am buying another for my husband. This is the fourth item bought from Back Market and we have loved them all. We will buy all of our electronics (if they carry them) from Back Market.

    First time purchase from Back Market. The entire process was painless and I had the phone in just a few days. Came in a small box very well packaged. I absolutely love this phone. I got one in Excellent condition and it definitely was. Absolutely no scratches or signs of any wear on the screen. It originally booted as an ATT branded phone but converted itself to Tmobile when booted with the Tmobile sim card. Everything works on Tmobile. Tmobile Video calling, Wifi Calling, SMS with status notifications, etc.. I previously had a Galaxy S7 and this phone is literally life changing. It is amazingly fast. Most apps start in about 1 second sometimes less. I can now do so many more things. Download speeds on Tmobile 5G are 285 Mbit/sec. Battery life so far is excellent. So far getting over 1 day from charge limited to 85%. Photos are very good, Including close ups. The phone is an absolute joy to use. I paired the phone with a Spigen Rugged Armor case for a nice slim package. My only regret is not getting this phone sooner.

    It is a great phone with working functions. However when I had purchased the phone, I do believe it was locked to Tmobile. When I had received it, it was unlocked to AT&T and other carriers. I had spent more than 2 hours with tmobile to get the phone to authorize Tmobile to recognize it. I feel that if I search for a phone that is Locked to company, it should be locked.

    My recent experience has been unacceptable. The phone purchased was sent with a bad battery. Upon sending back for repairs, the seller claimed the phone had not been wiped and sent it back. Upon return, the phone was completely wiped and reassured us that we had done everything appropriately. We tried to live with the phone but it needed a new battery. We sent it back for repairs only to receive a battery charge bank with the seller claiming that's what we sent. This whole experience has been awful. When reaching out to Back Market for assistance, all we got was to contact the seller. This is a complete waste of time and money. I will never shop here again.

    Hello, I am very happy with my S20 overall. The one problem is taking a picture with a close up focus is a bit difficult. You can bring the pic closer, but not as close up as my old phone. Also, I am very unhappy with the trade in process of my old phone. The told me they would give me $10 for a trade in. I deleted all my old files, google and reset it to default settings. When they received they said I had not deleted by Google info and would only give me $5. Then to give me the $5 they want access to my bank account and social security number for the deposit. I am very angry about this and do not want to give someone else access to that information, especially just for $5. I wish I had never agreed to the trade in and just took it to a machine here in town which pays me cash for my trade in. Very unhappy with the trade in business that Back Market uses.

Reborn vs. brand new

Here’s what you help prevent on average by choosing a reborn smartphone over a brand new one.

171.1 lbs of CO2e

That's like driving an SUV from NYC to Chicago.

6.3 oz of e-waste

That’s around the weight of a baseball.

537.1 lbs of raw materials

That's like 20 dogs digging in your yard for a week.

20,341.2 gallons of water

That's like running a faucet for 3 days
