Thank you for supporting our product. 

When the products leave the factory, we carry out a strict check. Dust accumulation in the lens is related to the use environment, and it is inevitable that dust will enter the lens after a long time of use. However, through our efforts, a small amount of dust will not affect the projection effect. If you are affected by this, please contact our after-sales department for assistance. We apologize for any inconvenience caused.

If you need additional assistance, please contact our customer support team.
