Dear Customer, thank you for your comment. First, we apologize for inconvinience to you because of the late delivery. Second, we want to explain the reason why it's late. It's because this product is not produced by us. Our supplier promised that the relay can be ready within 1-2 weeks but they postoned for a long time. We will improve our supplier management system and provide our customer a better delivery time assurance. Kind regards, Haohao WEI Sales Manager
