I can noy fault my experience with Back Market. I ordered the phone at 8.30 am on thursday and it was delivered to Ireland by 12pm on the Friday, the next day. The phone is perfect. Amazing quality. I will definitely buy more.

Livraison extrêmement rapide (le lendemain de ma commande) et tout à fait satisfaisante. Plusieurs années que je commande sur BackMarket, je n'ai jamais été déçu !

Paid for a premium refurbished unlocked phone. When the phone came it was locked to another network. I had to return the phone leaving me with no phone for some days. I was not impressed. Will not use this site again.
