I'm so glad that I chose Elecrow! Before placing the order, I made complex requests and asked a lot of questions. But their team was absolutely patient in answering questions, whether it was about the material selection of PCB, process requirements, or delivery time, they explained everything very clearly, even if I was a first-time buyer, I could make a wise decision quickly. When I received the final product, I was really amazed. The packaging was very tight and the quality was impeccable. And, it is worth mentioning that they delivered the goods exactly as agreed, without any delays.
