    Absolutely fantastic, I was stocked on how quickly and efficiently everything went. Basically I crashed my previous iPhone 13 mini green and the whole backside was cracked - but everything else was functional. I looked up back glass replacement prices and then compared to BackMarket options and it was cheaper for me to trade my broken iPhone for the same refurbished phone rather than pay t replace the backside! I chose "fair condition" option for the new phone but when I received it I could not see any wear and tear at all - maybe a few unnoticeable microscopic bits upon examination with a magnifying glass - it feels like a brand new phone - the battery is better than my last phone and it is not cracked. This was a perfect solution for me who wanted to keep the original small phone and did not want to upgrade. Will definitely also get a refurbished laptop from these guys later when I need one because they do such a good job and it feels great not to give money to Apple again and fall into this scam with apple care. Bravo BackMarket - well done and looking forward to doing business later as well!

    I've been really impressed with the Galaxy S25 Ultra. The performance is excellent, the battery comfortably lasts all day, and the display is outstanding. The camera system is a significant step up from my previous phone, producing fantastic photos in a wide range of lighting conditions without needing to understand lots of camera settings. The S Pen is a useful addition, and the overall build quality feels premium. Despite having so many features, the phone is straightforward to use, which is something I particularly appreciate. Buying a refurbished device was also a great decision. The phone arrived in excellent condition, looked virtually brand new, and performed exactly as expected. It's reassuring to know I've saved money while also making a more environmentally friendly choice. Overall, I would highly recommend both the Galaxy S25 Ultra and purchasing a refurbished model. It's an excellent phone and represents fantastic value for money.

    Back Market Turned a “Refurbished” iPhone 12 Into My Daily Driver—And I’m Genuinely Blown Away I’ll be honest: when people hear “refurbished,” they usually expect compromises. Scuffs. Battery anxiety. That one annoying flaw you can’t unsee. This iPhone 12 from Back Market completely shattered that stereotype. I ordered a Product (RED) iPhone 12, 128GB, and what arrived felt less like a secondhand phone and more like Apple quietly sent me a brand-new unit on the side. Condition: The phone arrived in exceptional condition. The glass is clean, the frame is flawless, and if you told me this device had never been used before, I’d believe you without hesitation. No scratches, no dents, no “refurbished tells.” It looks premium because it is premium. Performance: This is where the iPhone 12 still flexes hard. The A14 Bionic chip is absurdly smooth—apps open instantly, multitasking is effortless, and everything from social media to photo editing runs without a hiccup. This phone doesn’t feel like it’s “keeping up.” It feels like it’s leading. Display & Design: The OLED display is gorgeous. Deep blacks, vibrant colors, and razor-sharp clarity that makes content pop. The flat-edge design still looks modern and feels solid in the hand. And the Product (RED) finish? Stunning. It’s bold, clean, and turns heads without trying. Battery & Reliability: Battery life has been excellent for daily use—calls, streaming, browsing, and content creation. This is the kind of phone you trust to get you through the day without babysitting a charger. The Back Market Experience: This is where the real magic happens. Back Market didn’t just sell me a phone—they delivered confidence. Clear grading, fast shipping, eco-friendly impact, and a device that exceeded expectations in every way. It’s rare to feel like you got more than you paid for, but that’s exactly what happened here. Final Thoughts: If you’re on the fence about refurbished tech, let this be the review that pushes you over. This iPhone 12 proves that smart buying doesn’t mean settling—it means winning. Back Market has officially earned my trust, and this phone has earned its place as my go-to device. This isn’t just a good deal. It’s proof that premium tech, sustainability, and performance can coexist—and absolutely thrive. Highly recommended. No hesitation. No regrets.

    I bought an iPhone 13 128GB Starlight ‘Fair’ condition phone for my daughter, and she is delighted with it. It has barely any scratches - only a small little one on the top left corner that is barely visible - and works as well as a new iPhone would. We had no trouble with it apart from when we first unboxed it and put it on to charge it took a very long time to fill up, but it charges absolutely fine now that she is using it more. I was so happy with my purchase that I ordered the exact same one for myself, as my old Honor 9 Lite was reaching the end of its life. There was no problem transferring and I and my daughter are both very happy with the purchases. We will definitely buy from here again, thank you BackMarket📱!

    I am very happy with my order. The phone is really ergonomic, light, and very easy to carry. The quality is great, and it looks beautiful. I truly love it. I ordered a Premium iPhone Air(light color) and it feels like it has never been used before. It is just like an open-box item. The battery cycle was at zero, there are no scratches at all, it is clean and everything is completely original with no replaced parts. It arrived safely in its original box. I've been using it for almost a month now, and I am extremely satisfied. This was my first time buying from Back Market, and the seller exceeded all my expectations. A big thank you to the seller.

    I ordered the excellent condition and it came looking brand new! I ordered it on Thursday and it came Saturday. Phone is in amazing condition, battery capacity is on 89% but I have no issues with that, seems good to me for a refurbished phone. I would definitely recommend this seller. Also a cable came in the box 👍🏼😁

    I have been wanting the iPhone 15 Plus for ages and now I finally have one. I purchased the condition as Excellent and it most definitely is, not a scratch or mark on it and the battery is great too. It runs smoothly and transferred all my data very quickly over from my old iPhone. Delivery was speedy too. Please do protect it though and purchase a case, a screen and camera protector. I’m so happy with it and I will definitely buy from BackMarket again. Pics uploaded and a short video regarding quality 🥰

    I bought the iPhone 15 Pro with a new battery. I received the iPhone in perfect condition even better than I expected for “fair condition” the phone has minor scratches on the front (as expected) and it is flawless from the back! I was sceptical buying from Back Market due to some negative reviews.. but it definitely is worth it and my experience has been very good. I am very pleased and happy with my purchase 😊 the iPhone came packaged well in a box with a leaflet which had important info, a charging cable and a SIM card opener. For the price it is definitely worth it and I will consider buying from here again for sure👌🏼 saved myself time and money 😁

    Perfect condition, not a single scratch or dent. Bought for my dad as he needed a new phone. He said the battery on this phone lasts a long time which is really good, he’s barely having to charge it. It’s also the same size an my iPhone 15 bro max so that’s also a benefit as it means he’s not having to look at a small screen. For the price, it’s deffo worth it. I first bought him the s25 but the screen was too small but this is deffo an upgrade
