Considering this mobile was over £1000 when new the price I paid was a fraction of that. It looks and feels brand new. Ok it's not supported by Samsung anymore, but put decent antivirus software on it and you'll be fine. Will definitely be buying from back market again.

Excellent. Second time buying from Back Market and I have to say I can't fault them. Ordered a phone this time for my husband, as he smashed his old one on holiday. Buying a reconditioned one from Back Market was cheaper than getting his old one fixed. Phone arrived in perfect condition, looked brand new! I'll definitely use this company again in the future.
