thank you for your sincere suggestion.I have idea now.
and a question,do you know TMART.COM?I would like to know how about it?
plz tell me if you know it.
To me that site looks like one of those imitation product selling sites, as it looks just like a site I shop at from time to time (DX). They get mock versions of a real product, or a non-licensed version of a product. In some cases, especially for things like phone cases, memory cards, flashlights and cheaper simpler products they can be nice (not always the case though). You get a similar product for a cheaper price. With the more complex products like say a phone, they tend to skimp in a few (or all haha) areas making the product overall much less desirable. Giving it a bad screen (resistive touchscreen), lackluster camera, poor battery, bad internal specifications, and non-existent support (no updates, maybe little to no warranty....etc). Sure some if not all of that can happen on a real phone as well, but it is almost guaranteed to happen with the knockoffs.
That said I didn't even see an actual phone on the site, unless you are looking at the watch phones. So I am not sure what you are looking at comparing a Sony to an HTC using that site.
