Was having major problems with my Samsung Galaxy S8 & took it to a repair shop. The battery was replaced, but that didn't help. The service tech at the shop told me about BackMarket. With the 30-day money back guarantee and 1-year warranty on the refurbished phone, I decided to give it a try. The phone arrived quickly, within 5 days. Although the condition was listed as "Very Good", it appeared flawless to me. I am still in the learning process for all the new features on this phone, but it is performing perfectly. At this point, I couldn't be happier with this purchase.
