I have bought refurbished phones for at least 12 or so years. I wanted a s20 ultra to replace my s9+. I had bought 2 other s20 ultras fro different places but they did not work out. This phone is a keeper and I will have it for 2 to 3 years. Great phone!!

This is the second time that I have ordered from BackMarket and I have been very happy each time. The phone arrived in 3 days time with no issues. I would recommend anyone looking to buy a refurbished phone to buy from BackMarket.

Excellent delivery on time , great product, exactly what i ordered ,however (and this may be because this was my first time buying a refurbished device) but i had to unlock it myself due to it still being locked to att this may be something i as the customer should have researched beforehand but im not too swayed by that since the process of unlocking a device from att is actually quite simple easy and free courtesy of ATTs network unlocking request system but definitely something i didn't expect i had to do and luckily I didn't fall for the people charging for doing that. But otherwise the phone is excellent great condition works phenomenally battery life is practically speaking also phenomenal no shadows no on screen scratches or imperfections all around smooth and great purchase.

Excellent. I first purchased on Amazon refurbished and received a poorly functioning locked phone from them. I then purchased from Backmarket and received an excellent phone quickly.

The S20 Ultra is perfect and no one would know it had been refurbished, it's a great model: light and with lots of features. I am very pleased with my purchase from Back Market! Thx!

This is my 3rd purchase from Back Market. Every phone has been exactly as described. This S20 Ultra is like new. The screen is immaculate and the body shows no scratches or wear either. The battery life is impressive. I like that it is backed by a 12 month warranty. I had no trouble transferring my data from my old phone with Samsung Switch. So far so good! I'll be looking to upgrade my daughter's phone soon, and will be coming back to Back Market to do so.

Ordered a Samsung S20 Ultra 5G phone. Received order in a timely manner. Packaging was very good. Phone received was in excellent condition. First time using back market. So impressed that I immediately returned to order a second phone for my wife. You may very well be my go-to store for personal electronics from here forward. Thank you.
