    It feels as if I got it from the Samsung store or website you really can’t tell if it was refurbished or not so the quality is astounding to say the least. The shipping was actually surprisingly fast considering how far it was from where I live so, big ups for that and they would update me as to where it was all time. Overall I am very happy with my purchase as I needed a new phone for a while but I didn’t want to spend almost my whole paycheck for one so, as far as refurbished items go, please keep delivering, thank you.

    Honestly a really good device, just not the right fit for me. I'm used to a larger screen and longer battery life, that's really the only things I didn't like and that's clearly not the phones fault, I would recommend backmarket and their refurbished devices to any and everyone. The previous device I had was also from BM bought almost 2 years ago it would still be being used had it not suffered water damage, they have excellent quality, value and selection and their customer service is better than any other smartphone retailer, they actually have a conversation feed between you and the representative so you don't have to worry about getting a different person or answer every time. Hands down the absolute best phone buying experience I've ever dealt with and I will continue to purchase into the future. Oh and don't forget about the prices, you'll save a ton of

    I will always use Back Market. The s21 is fantastic. Looks brand new. I love the pink color. If anyone is in doubt about refurbished items, do your research first. Back Market will always be my go too.

    Worth every bucks. Phone works really well, no scratch at all and in top notch condition. I will definitely recommend this product and back market as well. Simply awesome. Will save many bucks. Rather than new one, u can buy refurbished one from reliable source like back market Will do shopping in future as well. Cheers to this experience

    This is my second purchase from Backmarket. I'm obviously pleased with the quality and price of the phones I've received. I believe in the value of refurbished devices, and I'll surely continue to do business with Backmarket. Their emails are funny, and I'm happy to see a sense of humor in my mailbox! Thanks Backmarket!! 😎

    I loved how quick my new phone got shipped to me, how easy it was setting it up, and how it felt like I was getting a brand new phone despite being refurbished! I definitely recommend Back Market to all my friends and family!

    I'm not one to buy anything refurbished but as of lately I'm not trying to spend 1000 on a phone every 2 years. So I made the decision to get one from back market and I'm actually impressed with the phone quality and functionality. I am Def buying my next phone here again.and I promise if you get one from this site you will not regret it.
