This site so new barely 2 weeks old so I doubt anyone has used them here on the forum. Although I haven't used them personally, I can say that I will not recommend them to anyone.
They are based in Beijijng, China and selling high end electronic brand names. The likelihood of receiving a fake would be 9 out of 10 times in this scenario. If you do a bit of research here on the forum you'll find out that everyone agrees that China is not a place to buy branded electronics.
Don't be tempted by their product listings and prices.
I did a mock purchase just to check if they do accept PayPal - apparently they don't. They only accept western union, money gram and bank transfers, all unsafe payment methods.
Hope this helps :)
