Bought a high-end mobile from ZTE from this site. Sent me the wrong phone, refused for 2 weeks to accept this, eventually did (indirectly). Sent the phone back and received week after week of template-E-Mails telling they'd send the correct one etc. etc. They never did. The only way I got my money back was because PayPal took on the case. As it seemed, the seller stopped bothering to answer PayPal about whether they received the returned phone but I had copies of all documents as evidence.
Basically, nubiamobileshop.com behaved as scam-artists but ones that kept in touch. Good orders were good orders, if you believe the comments on their site (many written in the same style). Wrong orders were treated with contempt.
How long did it take to get the money back? 3 months. Use at your own risk. As I see from other review websites, others have had very similar experiences.
Oh, and the wrong device they sent originally? The English menu was grammatically, structurally and spelling-wise corrupted. Odd for such a large corp. as ZTE. The About Us section states it's a subsidiary of ZTE. It is not. ZTE official said so. Twice.
