Review on GoPro HERO9 (CHDHX-901), 23.6MP, 5120x2160, 1720 mA, black by Wiktor Gajewski ᠌

Some pros: The quality of the outside build (internal apparently not very good). Because of the following factors, it is not possible to evaluate the standard of the shot. One star is deducted for the quality of the overseas technical support. Many disadvantages: The following issues were present in the brand new camera just after it was opened: 1) Excessive warmth during the charging process 2) The battery is not charged to its full capacity (on the native 90%, on the purchased from the store 98%, don't dance); the maximum charge achieved is 98%. 3) The protection turns off the strong heating that occurs during recording, and not in the maximum resolution but in the 1080/60 setting instead. 4) Rapid discharge when capturing video (about 1.5% discharge for one minute of 1080/60 video). The 2022 store did not initially notice the issue, and instead provided the response based on its "expertise," which was that the camera needed to be calibrated. I notified the relevant authorities and shipped the defective GoPro camera to the Netherlands, where they replaced it with a brand new one but found the same issues. They have offered to mail it once more.
