The supplier has became untrustable. After doing business with them for almost 3 years, they finally made the things wrong, and were very unwilling to fix the problem. They sent me a wrong item, I never accepted this fact, even when I send them proof of their mistake. Fortuantely Alibaba provide me with my money back with their own pocket, because the supplier did not want to refund my money, Thanks a lot Alibaba !!! DO NOT MAKE BUSINESS WITH THIS SUPPLIER
