    Great 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

    great 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.

    I purchased the Galaxy S21 Ultra 512GB model in good condition and it did arrive in good condition indeed. Screen - mint condition. I'm very happy, only thing is I had to get a fast charger for it. Also, battery is somewhat average but in fairness I didn't expect it to be much better anyway (lasts about a day with medium usage). Shopping experience was absolutely fantastic 👌 💯 I would highly recommend this company to anyone.

    Delivered quickly. Software seems ok. Chip on phone's metal casing where it dropped or was scratched. Good value... Pity case didn't arrive with it. Waiting 2 weeks and still not delivered

    It says I received the package and I still haven't received anything. It's a scam.
