Based on my experience with Yoybuy so far, I'd say it enabled and really facilitated my purchase of overseas products.
The items were promptly bought on the same date of order. It didn't take long for their arrival. It was most important that quality was examined before delivery.
When I had questions with orders, I received timely and helpful responses from agents via live chats. Although the shipping cost was a bit high, there were discounts for DHL and EMS.
Overall, using this site was an enjoyable process.
