    this little phone is so fun! i got it and its in great condition, couldn't even tell if it were brand new or refurbished. it took a little bit to get used to, the flip action brings back memories though. The screen has a few new dents from my keys in my bag but thats my fault, thought they'd go away but nope, still there. i got tons of comments from my family and coworkers asking me what i was using haha! happy birthday to me :D

    This was my first time ordering a refurbished smartphone on Back Market and I gotta say, I'm 100% satisfied with my Z Flip4. I was VERY hesitant on buying a phone on here. I was also a bit worried that it wasn't gonna be unlocked or in the color I ordered based off of other reviews but I was able to connect my service to my phone and it came in the color I ordered. Camera quality isn't the best but I didn't buy the phone for that so it doesn't bother me that much. I bought it in good quality and looks almost new and I'm impressed with thats. It's been over a week since I've gotten the Z Flip4 and I've been pretty happy with it. No problems at all so far. Thank you, Back Market.

    I was skeptical about ordering a refurbished phone due to my iPhone 11 cracked....I took a chance with back market and I have to say I'm in love. I think moving forward going to get all future phones from here!!! I chose the fair option, phone had no scratches anywhere!!! Was able to setup and transfer most of my things from IOS back to android. I'm in love!!!!! Phone is basically brand new. Got many compliments. Very satisfied customer. Thank you!!!

    I made the switch to Samsung because of Min Yoongi I'm gonna be honest. Him smiling on the front row had me going wow he REALLY likes this company. I'm not a heavy phone user. It's why I have used a 5s iphone since it came out and I only upgraded to a iPhone SE 2020 because my job that paid me barely over $12 kept saying my phone was too small. Imagine that. iPhone SE 2020 too small to STOCK GROCERIES ON A SHELF. That's the miserable world we live in. I quit that job and kept the iPhone but again, I'm not a heavy user. I literally use it as a glorified alarm clock. I'm the person who had an iPod shuffle and miss it. The little clip on one. Anyways I said when I do upgrade, I'm getting refurbished because HELLO I am team PLANET. Hence why I use my electronics until I literally cannot. I recycle so much I made that the symbol on my cat's id tag. I LOVE upcycling and everything I really do. Moving on to the phone review if you are still here. I'm gonna be COMPLETELY honest. I got the phone because it flips. I love tiny phones that close. I like opening my phone and closing it. I made several calls and thought, hmm, maybe talking on the phone is ok. Not really cos everything NOW ...

    I ordered the galaxy z flip4 256gb dark purple, I was very excited to receive it earlier than expected, I set it up with my network and I am so happy it worked immediately, I tried 2nd hand phones before, but all disappointments, I am so glad I found you Back Market, you guys rule, the phones are practically brand new, and ran like new, very very satisfied, I will be shopping from you again whenever I want an upgrade. Thank you back market

    Buying experience on Backmarket is superb. I got the Galaxy Z Flip4 256gb in perfect condition for 1/3 of the price. Only down is that the battery does not last as long as if it was brand new, but it can still hold a full day of normal usage.
