I got the phone in excellent condition, and I’m genuinely impressed. The shipping experience was solid — it arrived even before the estimated delivery time. I highly recommend buying from Back Market, especially for refurbished phones. They offer great deals and, most importantly, have strict policies to ensure customer satisfaction. Definitely a 100% recommendation.

I ordered 2 phones for my husband and I and both came in excellent condition and both locked to AT & T, which I was worried about, because we got an unlocked phone before that wouldn't work with our network, but these worked right out of the box, and flawlessly I may add! We are extremely happy with our purchase and will definitely buy again!!

I bought an excellent S21 FE from Cellular Gallery Inc. and am pretty disappointed in them. In all, it took over three weeks of waiting between a shipment not sent to a rough-looking phone with a nonfunctioning display to have them finally decide to give me a refund. If you have the time and money to wait, I suppose you can buy from here if it's a good deal, but overall having to work through the process with Back Market was long, not fun, and something I certainly wouldn't suggest compared to Amazon or Samsung refurbished. But hey, after wasting three weeks of my time, they gave me a 5% discount to spend on the now 40% higher-priced phone.

Great phone for an awesome price. Other than minimum scratches on back of phone it looks brand new and perform like new. I have bought several phones from here for my family over the years and will continue to do so.

My 3rd purchase from backmarket. Got an iPad, my last phone (dropped and broke the screen) Again I couldn't be happier with the quality & deal I got om this Samsung. It cost the same to upgrade my Samsung as it would to replace the OEM screen. I'm using it now to leave this review. No signs of wear on the device at all and battery life is great. Anytime i hear of someone shopping for tech, I recommend this site. It's great for newer models and phenomenal when your looking to purchase for your kids,etc. Ill be back to upgrade my daughter's phone.
