The delivery is fast, the track is tracked, increases normally, but you need to look at a certain angle, then only the image is displayed to the very edges. The lens is plastic, the inner side is smooth, the outer refrained and there are no glare, although the photo is unclear, the quality of the video does not spoil. In general, I liked it, an interesting thing. And the case is by the way wooden, not plastic, cool thanks to the seller Good
