I've had this phone for about 2 weeks now and I love it! I'm so glad my bf told me about Back Market because I've always wanted to experience the Z Flip and now I can at such a good price! The phone functions perfectly, it's sleek, stylish, and just small enough to fit in my pockets without worrying about it falling out lol. I'm absolutely living for the hinge mechanism and makes me feel a little closer to the 2000s flip phone phenomenon ♡

Device in pristine condition! Screen and battery life seem good after a few weeks of use, and no visible dents or dings on the rest of the device! Setup was simple for transferring my T Mobile plan and photos/contacts. Def recommend using Back Market for a pre-used phone, this process is so much smoother and cheaper than going to a phone store. However, the screen protector (provided by Back Market) on the Galaxy Z Flip4 peels up when I bend the phone closed, and some dust/hair has already gotten in. Will likely need to replace the screen protector soon, or just remove it entirely. Something to keep in mind for this specific phone type.

Close to perfection. The body may have tiny micro-scratches. For items with screens, the screen will be flawless.

It was very easy to set up, which I did for my husband since I bought this as a gift. It is a perfect phone for him, very fancy folding in half! Best "modern" feature, he can use the Square app to receive payments without a peripheral device. This is our 2nd purchase from BackMarket!!!

Great so far, looks and operates like a brand new phone. No issues turning on with my service provider. No scratches or marks. Great price. Very Pleased At This Moment. Well give it 6 months to 1 year then I'll know for sure.

The phone works fine enough. It starts and the screen turns on after like 10 clicks of the button. The screen turns to static and discolors a few times a day. When I paid for a 'fair' condition, I thought I was only for the outside phone quality. Because that's pretty much what the description of 'fair' reads as.

It came in the mail very quickly. Full disclosure I did pay extra to get it faster but it came fast than even the expected delivery. It looked brand new. I haven't had any issues with it. I know I was worried about the hinge mechanic but honestly it seems like as long as you are soft about shutting and opening it you wont damage the phone screen or hinge. I love how customizable it is and don't regret from switching from apple to this phone! Highly recommend!

The phone has the typical scratches I expected on the outside screen. Inside screen is perfect as is the case. The functioning of the phone has been flawless. Zero issues this far. But note to anyone buying a used or refurbished phone. BUY THE INSURANCE. It gives you peace of mind to know you are covered. I would recommend buying a phone or other product these folks sell. 100% satisfied.
