Verified purchaseGreat purchase on my end, I was still using the S9 before this so it was due for retirement unfortunately, still love my S9 though. This S21 is better in several ways. even being refurbished. it charges in a bit over an hour, the back is plastic so you don't need to worry about the phone flexing in your pocket and cracking, an issue I ran into with my old S9 partly because I procrastinated getting a case. The cameras on this are great, the quality is nice, and I'm not sure which processor it uses but it runs really smooth. It's got the average 60 hertz display and the fast and snappy 120 hertz display that you can cycle through, 9/10 phone imo

Verified purchaseThe phone was in excellent condition. I had no issues swapping phones and have run across no glitches. I am very pleased. As someone who doesn't need the newest item, just a good functioning one, I am pleased to find a place I can find refurbished items without worry.

Verified purchaseCame a day earlier than tracking said it would, so I almost missed the package. But it came fully charged and immediately ready to be set up. Screen has no damage; neither does the body. Touch sensitivity is a bit off, especially around the edges, but not sure if that's an issue with the model or just this singular phone. Battery drains so quickly while in use, but it's pretty expected with refurbished stuff. Jumped from the S8 to the S21 so it's a bit too get used to, but everything seems to be in good working order.

Here’s what you help prevent on average by choosing a reborn smartphone over a brand new one.
That's like driving an SUV from NYC to Chicago.
That’s around the weight of a baseball.
That's like 20 dogs digging in your yard for a week.
That's like running a faucet for 3 days
