In my search for a new action camera I decided to buy the SJ Cam 8 Pro from Amazon. The specifications looked good including optical image stabilization and better battery life than its competitors. However, on the three cameras I received from Amazon, the front display never worked on two and on the third it failed after a couple of days.
I have heard that there have been problems with copies of the SJ Cam being distributed. I have no idea if the three cameras I received were illegal copies or not. The packaging and included accessories appeared to be genuine. Whatever the reason, the three cameras I received were unreliable, so I decided not to buy a camera made by SJ Cam again.
