Dozens of cheap Q10 cases from Chinese site: Buychina.com. Are china cases reliable?

I find the site through google several days ago, and purchase a Q10 case from it: buychina.com.

and I have got my order tracking number, it is on the way to singapore now.

I also find more blackberry cases as follow site category page:

Wow, there are nearly 4957 cases of "blackberry"
Seems their items are quite rich and cheap in cell phone cases.

what do you think about it?

Anyone has purchased cases is better, hope can get your reply timely here.

Thanks for any share.
