Thank you very much for your interest in the product. I am selling it because I have had fewer opportunities to use it. I purchased it from the official store about a year and a half ago. I have used it about 20 times, and the shooting time is probably about 5 hours. The lens cover has been replaced with a glass one. Because of the glass lens cover, the image quality is considerably better, and the durability has also improved. There is one scratch on the corner, although I don't remember dropping it. There are no practical problems, and it hasn't spontaneously broken or had a fast battery drain. The included items are all those in the second image, including the stick. The SD card has been removed, and the main unit has been reset. - Model Name: Insta360 X4 - Resolution: 8K - Camera Type: Action Camera - Accessories: Warranty, Instruction Manual, Lens Cover - Waterproof: Yes
