never heard of that site so i did some googling. one of the sites i came across had some discouraging comments
http://www.danviews.com/gearbest-com-must-reads-about-the-chinese-online-gadget-store/
have you ever ordered from gearbest?
That site needs to declare that it is using affiliate links with Gearbest, which is obviously the reason for the positive review.
The problem with cheap sites like Gearbest are that to stay cheap, they use the cheapest form of international mail. Given the propensity for postal workers to steal items, as well as what seems to be a lack of understanding about how poorly mailed items will be treated by those workers, they end up with a great many lost or damaged packages, a lot of pissed-off customers, and a bad reputation.
There were similar issues in the classifieds for a while. Some unaware person would sell their headphones to another member from SomewhereOrOther-istan and send them via regular mail without tracking. Of course the receiving postal workers will say "Ha! No tracking! Free headphones for me!!!" and they never arrive.
