美国采购需求：夜视镜

I'm reaching out because I'm experiencing a significant blurriness issue with my equipment. I've tried a few troubleshooting steps, but the problem persists. I was hoping you could provide some advice on potential fixes or adjustments I could make. Additionally, I wanted to know if your company offers service options or replacements for this model. It would be great to get clarity on what steps I can take moving forward to resolve this issue. Thanks!
