Thank you for your support of our products.

When we ship our products, they undergo a strict appearance inspection. Dust in the lens is related to the usage environment, and after prolonged use, some dust may enter the lens. However, through our efforts, small amounts of dust do not affect the projection functionality. If it impacts your user experience, please contact our after-sales service for assistance.

We apologize for any inconvenience this may cause.

If the above solutions cannot solve your issue, please contact Nebula Customer Support at support@seenebula.com for further assistance.
