The phone was as described in the site for Premium grade - like new. Everything works as it should - I am very happy with the purchase! Definitely recommending the sellers.

love the phone. excellent condition. one issue though, it had not been fully factory reset so still had many apps (Spanish) installed and phone language was set to Spanish. Apart from this minor inconvenience, it's a great phone at a very good price.

I spent several days searching for the best deal and found black market was the cheapest in fact it was €90 cheaper than The number one ref Farb website. Delivery everyone else was five days where with black market it was only two.: will definitely be using again.

Its been up and running for a few days and it seems almost perfect. Except for a very light scuff mark on the back cover, I can't tell it from new. The phone was dispatched quickly and delivered via a tracked service with one of the big couriers. The price was good, especially considering S23 Ultras seem to be holding their values well. My only slight disappointment was at the time of ordering - a 12gb RAM version was not available. The S23 Ultra is the last Samsung to have a 10x optical zoom on the camera so I'm delighted to get such a good example.

Got the excellent condition model and you'd never know it's not brand new. I'm delighted with it, this feels like a brand new phone, battery is in great condition. Will never buy a brand new phone again.

Brilliant device, may as well be brand new! Only issue is the S-pen is really stuck in there and needs an implement to remove.
