Initially I was nervous about buying from this site but I had nothing to worry about! The phone I ordered came in great quality compared to my old phone (same model). This phone is really good, my old phone lasted me for roughly 4 years (the longest time i've had a phone for), it has an amazing camera on it and can wirelessly charge. The wireless charging feature helped my old phone last that long since the charging port had broke (due to being dropped whilst charging). The phone had a good battery life when I recieved it meaning I didnt have to charge it first to try it out. The price for this was amazing,especially with the quality differences compared to other places e.g. amazon or CEX. I even managed to get this phone for cheaper using a student discount, which i'm really happy about. The order came really quickly than estimated (less than 2 days after ordering with free delivery) and came with a charger and a phone case; I wasnt expecting the phone case. I would definitly recommend!

Can’t fault the phone, was delivered quickly with plenty of updates, it works as expected, battery life is still good. The only issues I’ve had and occasionally still have are details/logins for the previous owner still being present. Surely a factory reset would have sorted, I dont’t know….

I did not have to wait long for the phone. It's nice. On loading it acted promptly. I have been able to download a few more apps. It was working well so far. Great buy. S. Abbas
