波兰采购需求：智能家居设备解决方案、遥控和无人机解决方案、直流大电流内部连接插头、Amass Electronics、碎木机连接器、吹雪机连接器

I've recently acquired a couple of your connectors, but I've noticed that neither of them has the "Amass" branding on the housing. This has raised some concerns about their authenticity. Could you please confirm whether these products are genuine? Additionally, I'd appreciate any guidance you can provide on how I can verify their authenticity. Thank you for your assistance!
