I've been using DHGate for the past couple months, and am really impressed with their system.Excellent website / ordering process, and the important point I learned after a package wasn't sent, is that they hold your payment in escrow until you confirm your package arrived and was as described, and the seller doesn't get anything until you approve.
I'm really impressed, and their phone app is really good as well. My only issue with DHgate is not with them, it's the sellers descriptions of the products.
They use too many keywords to get search rankings, and it makes confusion about model names / brands / features etc.You really need to do your homework before committing to purchase on certain items like electronics and such.
