4.9/5I was really surprised to see my new phone was in absolute perfect condition. I really had to examine the phone thoroughly to find even the tiniest of a mark. The shipping was bang on time and the packaging was very good too. I'll definitely be using Back Market next time also.

4.6/5great phone, like new. the only problem I have us when I was ordering I looked up the specs and it said it was a G988b, which is the European version firmware. I wanted this because I had already bought the same phone from refurbed.ie and they sent me a G988u1 phone, the problem was it's on US Firmware and I could not get it to update to latest firmware. they took it back and promised me a replacement but never followed through. this phone even though it's set to USA region firmware has updated ok, but only downside it's only got American English version. I think you should only sell phones that have regional based firmware to the same firmeare region. for example I should have received a Gʻ988B phone.

5/5Great service.. quick delivery.. ONLY gripe if I had one was that we can't use Klarna on the page, which would have made additional purchases simpler. We had to use refurbed as they do offer that service and as a household of twelve we buy a LOT of phones so would make good business sense to adopt it
