So, Salehoo recomend o not this dropshipper.....He still in his Directory.
If you are referring to DHgate, then what you need to understand is that DHgate is a B2B directory, just like Alibaba, Trade Tang and so on. These sites feature suppliers who list there, they are not the supplier themselves.
When it comes to doing business on any B2B site, especially with a Chinese supplier, you need to research the supplier you are wanting to do business with, not DH Gate or the other B2B sites themselves.
Even if you do decide to go forward with a purchase from a supplier from one of these B2B directory sites, you still need to choose a safe payment option, and the safest of them all is credit card.
If you pay by credit card then you always have the option to file a chargeback on your purchase should you not be satisfied for whatever reason.
