Is Dhgate.com a reliable site?

Tweet

A friend of mine in a caribbean country wants to buy a dual sim phone from DHgate.com. So When I heard it was a chinese site, I was not to sure about it but then I scrolled down to see if they accepted paypal or credit cards and they do. So I was wondering if there was anyone in here who knows a little about the site and they can tell me if it is a respectable site.
