The appliance ordered arrived within the stated time. The delivery was well monitored, and we were informed at every stage.
The phone is in perfect condition, very well packaged in a blister pack with all the accessories, it looks like new!
On the other hand, I wanted cheap and I got cheap. The phone is archaic, you hardly need a stylus and a stone tablet to write a text message :-D. It's impossible to download apps, the internet is only 3G, so-so...
I'm not blaming Back Market for this transaction. I just made the wrong choice for my needs.
I'm going to look into ordering another one... from Back Market of course ;-)
