Designed for XGIMI MoGo 3 Pro: The XGIMI Magical Lens is designed to create an atmospheric and immersive space. Blurring or distortion of the image is normal. It is not recommended for prolonged viewing. You can enjoy a planetarium by displaying a starry sky in your room, even without a VR device. The snap-on design makes assembly easy. Unleash your infinite imagination with the exclusive XGIMI Wall feature: When you first attach the Magical Lens, a download message for the XGIMI Wall app will automatically appear. Please follow the instructions below to "Download". Installation: Attach the edge of the XGIMI Magical Lens to the side of the main unit's lens, align the bottom of the Magical Lens with the groove on the main unit, and then secure the latch to the main unit.
