I love my Galaxy S21, it is quite a bit larger than my last phone. I don't know why it took me so long to upgrade. Never disappointed with buying from Back Market.

Wow, kudos to Black Market for their novel approach to sales: selling brand new, flawless phones as 'refurbished'. I mean, who needs transparency, right? It's not like customers might feel misled when they get a phone that's literally perfect. But seriously... But let's talk about my recently purchased Samsung Galaxy S21 Ultra - it's a stunning device. The display is vibrant, the camera is incredible, and performance is top-notch. I mean, you'd never guess it's refurbished; it looks and performs like brand new! If you're in the market for a high-end device and want a brand new phone at a refurbished price (wink), I'd say go for it. Just don't try to tell anyone it's 'refurbished'. HA! Product: Samsung Galaxy S21 Ultra Rating: 5/5 stars (for the product, and the sales pitch)

I was very sceptical about buying a refurbished phone, but after reading other reviews I took the chance and I'm glad I did. I purchased for my wife so that we can have the same phones. The only issue, may not be an issue, is there is three permanent light hard to see rings, about the size of a small button on the screen, it's only visible in photos when looking at pictures, other than that, the phone is perfect. I highly recommend others to purchase their phones through back market.

This is so super great, when i had it this phone it makes me happy that i bought my dream phone that i earned. I don't have to waste a thousand dollar for this phone. The performance was so great you won't realize that is a refurbished after all, from the good pictures of taking photos on camera to the perfomance when you take so much apps. For the great price of 200 dollars you can have a great phone for taking pictures and high graphics on playing online games.

This is a great backup phone. Despite the "fair" condition it only has a scratch on the screen which isn't noticeable while using it. The functionality it's perfect and what I expect from a Samsung S series.

I was a bit hesitant to order my phone at first since I’d never bought a refurbished device before, and I had seen a few negative reviews on social media. But I decided to give it a try, and I’m so glad I did! The shipping was quick, the phone looks brand new, and it runs perfectly — you’d never guess it’s refurbished. I’ll definitely be ordering again!
