Customer service good!
Well, I actually haven't received the product yet, but their customer service left a good impression on me. The item I purchased was supposed to be delivered to India, but I still haven't received it. After contacting the customer service to confirm the situation, the refund process was very fast. I still really want the product I bought and hope that they can open a stable shipping route to India in the future. So far, I'm quite satisfied with their response time.
