I used their website for a month it has these cons:
1- Long processing time, many of my orders took more than 4 days to get the tracking number.
2- Expansive shipping with long time delivery, the cheapest method it took 20 for delivery to US cost $10 & DHL cost $24/item.
3- They charge you Paypal Fees on any order you pay by Paypal.
4- They use their company name and they add it to each shipped item which makes your customer knows that you're a drop-shipper and these products not from you. So, it is like you market their business and their products.
